The Virtual Camera (or VCam) Component provides a modular system for editing a Cine Camera component using UMG widgets. The VCam Component is the base component for building a custom virtual camera in Unreal Engine like the VCam Actor. The benefit of building your own VCam is that you can implement custom functionality through Blueprint using Modifiers and Output Providers.

Virtual Camera Architecture

The VCam Component implements three aspects to its architecture: model, view, and controller.

  • Modifiers represent the model. These implement the logic for changing properties on the Cine Camera Component. Modifiers contain Connection Points, and they can optionally expose Input Actions (Enhanced Input), which can be invoked by UMG Widgets.
    • Output Providers are the views. They create and render widgets (possibly streaming them). Usually, output providers create UVCamWidgets, which are special widgets that can connect to Connection Points of Modifiers. Widgets interact with Modifiers in two ways:
      • Simple - Trigger input actions that modifiers are subscribed to and expose via connections.
      • Advanced - Queries whether modifiers implement certain custom defined interfaces.
  • UVCameraSubSystems exist for as long as UVCamComponent is enabled. This is comparable to LocalPlayerSubSystem.
    • One notable such system is the InputVCamSubsystem, which allows UVCamComponents to bind to input devices similarly to how Player Controllers do in shipped games.

Requirements and Prerequisites

To proceed with this guide, you must first have:

  • Followed the "Required Setup" sections of the Controlling a Virtual Camera Actor using Live Link.
    • Enabling all necessary plugins in your project.
    • [Optional] Using a supported iOS device.
    • [Optional] Downloading and installing the Live Link VCAM app from the iOS App Store.
    • [Optional] A shared network connection for your Unreal Engine project and your iOS device running the Live Link VCAM app.

Some Output Providers require use of an iOS device. For more information on their usage, see the VCam Output Providers section of this page.

Setting up a Custom Virtual Camera Workflow

Virtual Cameras are made up of two components: a Cine Camera and VCam. These two components are the starting foundation of building a working customized virtual camera.

To build a custom virtual camera:

  1. Add a Cine Camera to the scene using the Place Actors panel in the Level Editor.
  2. With the Cine Camera selected, go to the Details panel, click the Add (+) component menu, and select a VCam Component from the list.
  3. Click and drag the VCam Component onto the CameraComponent so that it is a child of the Cine Camera.

Your Virtual Camera will not function if the VCam Component is not a direct child of the CameraComponent.

Your Components hierarchy should look like the example below:

VCam Component in CineCamera hierarchy.

The VCam Component has the following properties:

VCam component properties.
Property Description
Enabled This toggle enables and disables the entire VCam Component.
Role Specifies the type of role to assign to this virtual camera in a virtual production environment.
Live Link Subject This is the subject used through the Live Link plugin. The component uses the subject`s camera information to drive the camera in the scene from the Live Link-connected device.
Viewport Locker The viewport that is rendered from the point of view of the virtual camera.
Disable Component when Spawned by Sequencer Disables the VCam Component when spawned by a Sequence. This prevents a situation where two VCam Components might become active at the same time when playing a Sequence that contains a VCam Component set as spawnable.
Input Profile Specifies the profile to use that has mapped inputs of the virtual camera. To learn more about Input Profiles, see Controlling Inputs to Virtual Camera Controls.
Input Device Settings Enable and Disable what can be used as an input device (keyboard, gamepad, and mouse). You can also select the type of logging for inputs.
Output Providers Contains a list of all output device destinations. For more details, see the Output Providers section of this page.
Modifier Context An optional object that contains arbitrary data that is shared between all Modifiers.
Modifier Stack Contains a list of all Modifiers added to the component. For more details, see the Modifiers section of this page.
Advanced Settings  
Disable Output on Multi User Receiver Disables the output if the virtual camera is in a multi-user session and the camera is the receiver from the session.
Update Frequency Indicates the frequency at which the camera updates are sent when in multi-user mode. This has a minimum value of 11 milliseconds. Using values below 30 milliseconds is discouraged. When higher refresh rates are needed, consider using Live Link Rebroadcast to stream camera data instead.

VCam Modifiers

Virtual Camera Modifiers are specialized Blueprint assets. They contain logic and Input Actions to build custom functionality. You can use them to create unique effects and behaviors (in Blueprint or C++), like camera shake, making focus adjustments, and limiting camera movement along an axis.

Virtual cameras can have any number of Modifiers applied to them to create a stack of modifiers that apply different behaviors and effects. Each modifier in the stack is applied and rendered in the order from top to bottom.

Unreal Engine includes a set of default Modifiers that are used with the standard VCam Actor. You can explore each of these Modifiers and their logic. You can find them in the Engine > Plugins > VirtualCamera Content > Modifiers folder.

VCam Output Providers

The Virtual Camera Output Provider system reroutes the output of the Virtual Camera onto various providers, such viewports, and devices using remote session protocols.

The following Output Providers are available to choose from:

To add Output Providers to your Virtual Camera:

  1. Select the VCam Component of a Virtual Camera.
  2. In the Details panel, navigate to Output Providers section, and click the Add (+) icon to add a new provider to the stack.

  3. Use the dropdown selected next to the added Index [0] element to select one of the Output Providers in the list.

    Adding an Output Provider to a VCam component.

    Each Output Provider in the stack applies and renders in order from top to bottom.

Viewport Output Provider

The Viewport Output Provider takes the view of the virtual camera in the scene and outputs it directly to the viewport of the Level Editor.

The Viewport Output Provider includes the following properties:

Viewport Output Provider properties.
Property Description
Is Active If set, this output provider executes every frame.
Target Viewport Select which viewport to use for this virtual camera.
UMG Overlay The UMG class to be rendered by this output provider.
Use Override Resolution

Override the default output resolution with a custom value.

For this to take effect, you must toggle Is Active off then back on.
Override Resolution Applies a custom resolution when Use Override Resolution is set.
Gameplay View Target Policy

In game worlds, such as Play-in-Editor (PIE) or shipped games, this determines which player controller whose view target should be set to the owning Cine Camera Actor.

Multiple output providers may have a policy set and policies might choose the same player controllers to set the view target for. This conflict is resolved by checking if a player controller already has the Cine Camera Actor as the view target, and if it does, the policy is not used. This means you can order your output providers array in the VCam Component as needed, and the first policies will get higher priority.

Pixel Streaming Output Provider

The Pixel Streaming Output Provider outputs the Editor viewport to a remote device connected using WebRTC, which includes the Live Link VCam app used with iOS devices. This method works with any compatible device that can receive streamed data, including web browsers. It is the primary output provider for virtual cameras.

Pixel Streaming is configured on an instance of the Pixel Streaming Output Provider and requires no additional setup. The VCam Component only supports a single stream.

The Pixel Streaming Output Provider includes the following properties:

Pixel Streaming Output Provider properties.
Property Description
Is Active If set, this output provider executes every frame.
Target Viewport Ses which viewport to use for this virtual camera.
UMG Overlay The UMG class to be rendered by this output provider.
Use Override Resolution

Override the default output resolution with a custom value.

For this to take effect, you must toggle Is Active off then back on.
Override Resolution Applies a custom resolution when Use Override Resolution is set.
From Composure Output Provider Index If you're using the output from a Composure Output Provider, specify it here.
Match Remote Resolution When enabled, the streamed Unreal Engine viewport matches the resolution of the remote device.
Enable ARKit Tracking Controls the corresponding Cine Camera Actor with transform data received from the Live Link VCAM app on your iOS device.
Prevent Editor Idle Prevents the Editor from moving to the background when it is not the foreground application. This can make the editor unresponsive or sluggish when it's minimized or another application is being used.
Auto Set Live Link Subject When enabled, the Live Link Subject of the owning VCam Component is set to the subject created by this Output Provider.The Provider must also be enabled.
Streamer Id Set the name of this stream to be reported to the signalling server. If none is supplied, a default is used. We recommend that you give each stream a unique name, since you can run into issues if a streamer ID is the same as another VCam's streamer ID.
Gameplay View Target Policy

In game worlds, such as Play-in-Editor (PIE) or shipped games, this determines which player controller whose view target should be set to the owning Cine Camera Actor.

Multiple output providers may have a policy set and policies might choose the same player controllers to set the view target for. This conflict is resolved by checking if a player controller already has the Cine Camera Actor as the view target, and if it does, the policy is not used. This means you can order your output providers array in the VCam Component as needed, and the first policies will get higher priority.

Unreal Remote Output Provider

The Unreal Remote Output Provider outputs the primary viewport to a remote device connected using the Remote Session Protocol, such as the Live link VCAM app on an iOS device.

Unreal Remote requires additional configuration of your project to connect to an external device using a remote session. For more information, see the Set Up an Unreal Remote Output Provider section of this page.

The Unreal Remote Output Provider includes the following properties:

Unreal Remote Output Provider properties.
Property Description
Is Active If enabled, this output provider executes every frame.
Target Viewport Select which viewport to use for this virtual camera.

For this to take effect, you must toggle Is Active off then back on.
Override Resolution Applies a custom resolution when Use Override Resolution is set.
Gameplay View Target Policy

In game worlds, such as Play-in-Editor (PIE) or shipped games, this determines which player controller whose view target should be set to the owning Cine Camera Actor.

Multiple output providers may have a policy set and policies might choose the same player controllers to set the view target for. This conflict is resolved by checking if a player controller already has the Cine Camera Actor as the view target, and if it does, the policy is not used. This means you can order your output providers array in the VCam Component as needed, and the first policies will get higher priority.
Port Number Network port number. You should only change this if you're connecting multiple Remote Session devices to the same PC.
From Composure Output Provider Index If you're using this output from a Composure Output Provider, specify it here.

Media Output Provider

The Media Output Provider sends the output of a virtual camera to any device supported by the Unreal Media Framework, such as video capture cards from Black Magic and AJA.

Output Config Assets are used to specify the type of media source being output and its parameters needed to output to the source. For more information about these types of assets, their usage, and which sources are supported, see Media Framework.

Override Resolution Applies a custom resolution when Use Override Resolution is set.
Gameplay View Target Policy

In game worlds, such as Play-in-Editor (PIE) or shipped games, this determines which player controller whose view target should be set to the owning Cine Camera Actor.

Multiple output providers may have a policy set and policies might choose the same player controllers to set the view target for. This conflict is resolved by checking if a player controller already has the Cine Camera Actor as the view target, and if it does, the policy is not used. This means you can order your output providers array in the VCam Component as needed, and the first policies will get higher priority.
Output Config Assign a Media Output Configuration asset using one of the output sources supported by the Media Framework.
From Composure Output Provider Index If using this output from a Composure Output Provider, specify it here.

Composure Output Provider

The Composure Output Provider sends the output of a virtual camera to a Render Target. You can use Render Targets with Composure for compositing. You can use the Layer Targets property to specify a stack of elements to be used for compositing. Those elements support rendering UMG widgets.

The Composure Output Provider includes the following properties:

Composure Output Provider properties.
Property Description
Is Active If set, this output provider executes every frame.
Target Viewport Select which viewport to use for this virtual camera.

VCam Input Actions

Modifier Connection Points are an experimental feature.

Input Actions are mappable input from a Modifier Blueprint to hardware input. Enhanced Input is developed around the idea of mapping this hardware input to things like Virtual Cameras and remapping UMG inputs through the use of injection and Connection Points. You can use VCam Widgets (similar to UMG Widgets) like those for the Live Link VCAM app to control a Virtual Camera Actor in Unreal Engine. They are remappable to Modifiers without needing hard references or casts. Connection Points bridge elements to remap and reuse VCam Widgets.

Example of Configuring a Custom Virtual Camera

This part of the guide demonstrates the setup and configuration of a custom virtual camera using the VCam Component with a Cine Camera Actor through example. This process uses all of the elements discussed earlier in this page to build out an simplistic example to show how these parts interact and connect to one another.

In this configuration guide, you'll create and apply the following functionality to a custom virtual camera:

  • Create a custom virtual camera using Cine Camera and VCam components.
  • Setup Blueprints and logic that tracks a specified object in the scene using a virtual camera.
  • Expand the Blueprint logic to toggle on and off the virtual camera's ability to track an object.
  • Set up a VCam Widget to use the scripted Blueprint logic.
  • Further expand the Blueprint logic to change the color of the button depending on its state (on / off).

After following this guide, you should have a clearer understanding of how you can use Modifiers, Output Providers, and Input Actions with Connection Points to build out different effects and behaviors to use with a virtual camera.

Create a Custom Virtual Camera

To build a custom virtual camera:

  1. Add a Cine Camera Actor to the scene using the Place Actors panel in the Level Editor.

  2. With the Cine Camera selected, click the Add (+) component menu in the Details panel and select a VCam Component from the list.

    Building a custom virtual camera actor.
  3. Click and drag the VCam Component onto the CameraComponent so that it is a child of Cine Camera.

Your Components hierarchy should look like the example below:

VCam Component in CineCamera hierarchy.

Creating a Custom Modifier

In this section, you'll create a Modifier Blueprint. This Blueprint contains the behavior and logic that you can then apply to a virtual camera to create some effect. In this example, the Blueprint you'll create will be used to track a specified object in the scene using a virtual camera.

This part of the guide has been broken up into several smaller steps to build the VCam Modifier and follows this workflow to achieve the result:

Create a Modifier Blueprint

To create a VCam Modifier Blueprint:

  1. In the Content Browser, click Add (+) > VCam and add a VCam Modifier Blueprint Asset. Name it VCM_LookAt.

    Add a VCam Modifier asset to the Content Browser

  2. A prompt appears with the Select Input Mapping Context pop-up window. You can choose Skip.

    Select Input Mapping Context dialogue.

    See Enhance Input for more details about Input Mapping Assets and their usage.

You have now created a Modifier Blueprint, which you'll use for the rest of this guide.

Set Up Actor Reference Variables

In this step, you'll set up the variables used in the graph of the Modifier Blueprint. These variables specify the object in the level that the virtual camera will track.

When setting up this type of thing, any references to Actors in a scene must be defined in the Modifier Blueprint.

To set up your Modifier with Actor reference variables:

  1. Open the VCM_LookAt Modifier Blueprint.

  2. In the My Blueprint panel, locate the Variables category, and click the Add (+) icon to add a new variable.

    Add a variable to your Modifier Blueprint
  3. Click the text field for the variable and set its name to "TargetActor".

  4. Click the Boolean type, change its type to Object Types > Actor, and select Object Reference.

    Set the TargetActor variable to an Actor Object Reference.

  5. With the TargetActor variable selected in the My Blueprint panel, use the Details panel to check the box for Instance Editable under the Variables category.

    Set the TargetActor variable to be editable.

    Clicking the Eye icon next to the variable name does the same as setting Instance Editable in the Details panel.

The reference variables that you set up in this step are used later, when the Modifier is added to the virtual camera's Modifier stack. Variables that are set to Instance Editable are visible from the VCam Component's properties while working in the level. You directly set which Actor the virtual camera will track here.

Create the Modifier Blueprint Logic

In this step, you'll create some initial logic in the graph of the VCM_LookAt Modifier Blueprint. This logic is used to track an object in the world, using the TargetActor variable, by providing its location to the virtual camera. Unreal Engine uses this information to rotate the virtual camera to keep the object in view.

To add the logic to your Modifier Blueprint:

  1. Open the VCM_LookAt Modifier Blueprint.
  2. In the My Blueprint panel, locate the Variables category, click and drag the TargetActor variable into the Event Graph. Choose Get TargetActor.
  3. Drag off the output pin of the TargetActor node and add an Is Valid node.
  4. Connect the Event On Apply node to the Is Valid node.
  5. Drag off the Camera Component output of the Event On Apply node and add a Get World Location node.
  6. Drag off the Return Value pin of the Get World Location node and add a Find Look at Rotation node.
  7. Drag off the Camera Component pin of the Event On Apply node and add a Set World Rotation node.
  8. Connect the Is Valid pin of the Is Valid node to Set World Rotation node.
  9. Drag off the TargetActor node and add a Get Actor Location node.
  10. Drag off the Return Value pin of the Get Actor Location node and connect it to the Target pin of the Find Look at Rotation node.
  11. Drag off the Return Value pin of the Find Look at Rotation node and connect it to the New Rotation pin of the Set World Rotation node.
  12. Compile and Save.

The setup for your Modifier Blueprint is now complete and your graph should look similar to this:

Copy and paste the Blueprint code above directly into your VCM_LookAt Modifier to recreate the graph above in your own project.

You can use Reroute nodes to clean up the graph, making it easier to follow where wires are going. This is especially helpful when some pins have multiple wires coming from them or going to them. Double-click on any wire to add a reroute node in place. You can select it and drag it around like any other node in the level to reorient the wire.

Add Modifiers to VCam Components Stack

With the Modifier Blueprint completed, you can now apply it to the Modifier Stack of the virtual camera in your scene.

To add a Modifier to a VCam Component:

  1. In your level, select your created Virtual Camera Actor.
  2. In the Details panel, select the VCam Component in the hierarchy window.

  3. Under the Virtual Camera properties, locate the Modifier Stack, and click the Add (+) icon to add an element to the stack.

    Adding a modifier to the VCam Component modifier stack.

  4. Expand the properties under the added Modifier Stack element named Index [0], use the Name text field to name this Modifier "LookAt".

    Giving the modifier element a name.

  5. Use the dropdown list for Generated Modifier to select the VCM_LookAt Modifier Blueprint created earlier in this guide.

    Setting the Generated Modifier property.
  6. Expand Generated Modifier > Default to show its properties.

  7. Use the dropdown selection for Target Actor to select an Actor from your Level for the virtual camera to track.

    Use the exposed TargetActor property to pick an actor in the level.

    If you need an Actor to test with, you can use the Shapes Actors available in the Place Actors panel. These are simple shapes, such as a cube, cylinder, sphere, and cone.

You have now set up a Modifier Blueprint that you have assigned to your virtual camera to give it the ability to track that object wherever it moves in the scene.

Modify the Behavior of a Modifier

The VCM_LookAt Modifier Blueprint assigned to your virtual camera tracks the location of a specified object in the Level. In this section, you'll expand the scripted Blueprint behavior to add logic to toggle on and off the ability for the virtual camera to track objects.

To add additional behavior to your Modifier:

  1. Open the VCM_LookAt Modifier Blueprint.
  2. In the Event Graph, click and drag the Event On Apply node to the left to make space for additional logic before the Is Valid node.
  3. On the Event On Apply node, right-click the Camera Component pin, and select Promote to Variable from the list.
  4. In the My Blueprint panel under the Variables category, select the Camera Component variable.
  5. In the Details panel, expand the Advanced category, and check the box next to Transient.
  6. Connect the Event On Apply node to the Set Camera Component node.
  7. In the My Blueprint panel under the Variables category, click the Add (+) icon to add a Boolean variable. Name it "ShouldLookAt".
  8. Click and drag the ShouldLookAt variable into the Event Graph, and select Get ShouldLookAt.
  9. Drag off the ShouldLookAt node and add a Branch node.
  10. Connect the Set Camera Component node to the Branch node.
  11. Connect the True execution of the Branch node to the Is Valid node.
  12. From the My Blueprint panel under the Variables category, drag the Camera Component variable into the graph, and select Get Camera Component.
  13. Drag off the output pin of the Camera Component node and add a Set World Rotation node.
  14. Drag off the output pin of the Camera Component node and add a Get World Rotation node.
  15. Connect the Return Value pin of the Get World Rotation node and connect it to the New Rotation pin on the Set World Rotation node.
  16. Drag off the False execution of the Branch node and connect it to the Set World Rotation node.
  17. Compile and Save.

The added logic (highlighted below) uses a Branch node to toggle on and off the ability to track objects with your virtual camera. When the True path is followed, the camera tracks a specified object in the Level. When the False path is used, the camera stops tracking. This expanded logic only sets up what is needed to perform this behavior. The following sections of this guideuse this logic to track the Should Look Atstate using a VCam Widget for a button on screen to toggle this behavior.

Your graph for VCM_LookAt Modifier Blueprint should look similar to this one now:

Copy and paste the Blueprint code above directly into your VCM_LookAt Modifier to recreate the graph above in your own project.

Using Enhanced Input

Modifiers for virtual cameras can use Enhanced Input Actions to provide additional control to the VCam operator. In this section of the guide, you'll use these Enhanced Input Actions to control the keypress logic set up in the VCM_LookAt Modifier Blueprint to toggle on and off object tracking for your virtual camera. This means that a stage operator can press a key on their keyboard to use the functionality.

Create an Input Action

Using Enhanced Input Actions requires two assets: an Input Action and an Input Mapping Context. These assets are used to connect the keys being pressed with the logic set up in the VCM_LookAt Modifier Blueprint.

To create an Input Action and Input Mapping Context:

  1. In the Content Browser, click Add (+) > Input and add two items:

    Add an Input Action and Input Mapping Context assets to the Content Browser.
    • An Input Action and name it IA_ToggleActivation.
    • An Input Mapping Context and name it IMC_LookAt.

  2. Open the IMC_LookAt Input Mapping Context Asset.

    Open the Input Mapping Context asset.

  3. In the Details panel, click the Add (+) icon next to Mappings to add a new Input Action element to the array. Expand its properties and select IA_ToggleActivation Input Action created in the first step of this section.

    Assign the Input Action to the Input Mapping Context asset.

  4. Under the IA_ToggleActivation element, use the dropdown next to the Keyboard icon and assign the keypress S as the default key for this Input Action.

    Set the default key used for this Input Action.
  5. Expand the properties under the keypress assignment, and check the box next to Is Player Mappable.

  6. Expand the properties under Player Mappable Options and in the Name text field, call it "IA_ToggleActivation".

    Set the Input Action to Is Player Mappable and name it.

For more information on configuring an Input Mapping Context asset, see the Enhanced Input documentation.

Assign an Input Action to a Modifier Blueprint

In this part of the guide, you'll use the Input Mapping Context that you created in the previous section along with the VCM_LookAt Modifier Blueprint. You'll assign it to VCM_LookAt and set up some additional logic to handle which state the object tracking is in.

To assign an Input Action to a Modifier Blueprint:

  1. Open the VCM_LookAt Modifier Blueprint previously created in the Create a Modifier Blueprint section of this page.

  2. Select Class Defaults from the Blueprint toolbar.

    Click the Class Defaults option in the VCM_Lookat Modifier Blueprint.

  3. In the Details pane, under the VCam Input category, assign your IMC_LookAt Asset to the Input Mapping Context assignment slot.

    Assign the Input Mapping Context to the VCM_Lookat Modifier Blueprint.
  4. Right-click in the Event Graph and search for and add a IA_ToggleActivation node under the Enhanced Action Input. This event is named after the IA_ToggleActivation Input Action you created.
  5. In the My Blueprint panel under the Variables category, drag a ShouldLookAt variable into the graph and select Get ShouldLookAt from the list.
  6. Drag off the ShouldLookAt boolean and add a Branch node.
  7. Drag off the Triggered pin of the Enhanced Action Events IA_ToggleActivation event node and connect it to the Branch node.
  8. From the My Blueprint panel under the Variables category, drag the ShouldLookAt variable into the graph and select Set ShouldLookAt.
  9. On the Set ShouldLookAt node, uncheck the box next to the ShouldLookAt boolean. Do this twice so that you have two Set ShouldLookAt nodes.
  10. Drag off the True pin of the Branch node and connect it to the input of one of the Set ShouldLookAt nodes.
  11. Drag off the False pin of the Branch node and connect it to the input of the other Set ShouldLookAt node.

  12. On the Set ShouldLook node connected to the True path of the Branch node, check the box for the input pin Should Look At.

    Set up a branch for toggling whether the VCam should look at the selected object in the level.
  13. Compile and Save.

Having completed these steps, you have assigned the IMC_LookAt Input Mapping Context asset to VCM_LookAt. You have also added additional logic to determine whether the state of the IA_ToggleActivation Input Action is True or False.

Your graph should look like this now:

The graph with the branching choice for if the VCam should look at an object or not.

Copy and paste the Blueprint code above directly into your VCM_LookAt Modifier to recreate the graph above in your own project.

Be aware that with this particular setup, the input system executes anytime the 'S' key is pressed, even when the viewport is not in focus. This can cause conflict when someone presses the key for other purposes. For example, if someone renames an asset in the Content Browser that uses the letter 's', the event is executed.

Adding Output Providers to a Virtual Camera

The Output Provider system reroutes output of the VCam Component onto various providers, such as viewports and devices using remote session protocols. You can use multiple output providers for each virtual camera, and each does so in the order in which they are listed in the stack.

In this part of the guide, you'll do the initial setup and choose which type of output provider you'd like to use.

Initial Setup of an Output Provider

To add an Output Provider to a Virtual Camera:

  1. In the Level, select your Virtual Camera Actor.

  2. In the Details pane, locate the Components hierarchy, and select the VCam Component.

    Click the VCam Component in the hierarchy.

  3. Locate the Output Providers array, and click the Add (+) icon to add a new element, and select a provider from the Output Providers list. The settings for each type of Output Provider populates under their element when added to the array. Choose between:

    Add an Output Provider element to the stack.

  4. Check the box next to the Output property Is Active.

    Set the Output Provider to Is Active.

Not all Output Providers are set up the same. For information about each and any additional set up that they require to work with a virtual camera, see the sections below.

This guide uses the Pixel Streaming Output Provider as an example, including use of the required iOS Device and Live Link VCam app.

Set Up a Viewport Output Provider

The Viewport Output Provider list of properties looks like this:

Viewport Output Provider

To read about the Viewport Output Provider properties, see the Viewport Output Provider section of this page.

This provider takes the current view of a Virtual Camera and outputs it directly to the main viewport of the Level Editor. It can also display UMG widgets on the screen, like the example below. Use the UMG Overlay property to add the widget to the Output Provider. You can use the example asset TestUMG to see a working example displayed on screen.

Example of the Viewport Output Provider.

Set Up a Pixel Streaming Output Provider

This output provider requires a supported iOS device running the Live Link VCAM app.

The Pixel Streaming Output Provider list of properties looks like this:

Pixel Streaming Output Provider

To read about its properties, see the Pixel Streaming Output Provider section of this page.

With the Pixel Streaming Output Provider set, you can use the Live Link VCAM app on an iOS device on a shared network to connect to the level editor viewport and control the virtual camera. For a full walkthrough of setting up and connecting to the editor from an iOS device, see Controlling Virtual Camera Actors using Live Link.

Example of the Pixel Streaming Output Provider.

Set Up an Unreal Remote Output Provider

This output provider requires a supported iOS device running the Live Link VCAM app.

The Unreal Remote Output Provider property list looks like this:

Unreal Remote Output Provider

To read about its properties, see the Unreal Remote Output Provider section of this page.

This output provider requires additional setup in Unreal Engine's Project Settings and on the Live Link VCAM app to establish a connection.

Unreal Engine Setup:

  1. In Unreal Engine, open the Project Settings.

  2. Under the Plugins category, navigate to the UDP Message section and set the Unicast Endpoint to your computer's IP address with ":0" at the end to indicate your port number. For example, 10.0.0.0:0 would be the formatting.

    Set the IP address of the Unreal Remote Output Provider.

  3. In the Project Settings under the Engine > Rendering category, navigate to Default Settings, and set the Frame Buffer Pixel Format property to 8bit RGBA using the dropdown selection.

    Set the Frame Buffer Pixel Format to 8bit RBGA in the Project Settings.
  4. Restart the editor for these changes to take effect.

iOS Device Setup using the Live Link VCAM app:

  1. Open the Live Link VCAM app on your iOS device.
  2. Click the Gear icon in the bottom-right of the screen to open the Settings.

Passing Input Actions Using Connection Points

Modifier Connection Points is an experimental feature.

In the Using Enhanced Input section of this guide, you created an Input Action (IA_ToggleActivation) that can be passed through Modifiers to other Blueprints, like the VCam Widget Blueprint. You can use Connection Points to pass this input.

In this part of the guide, you'll:

  • Add a Connection Point in a Modifier Blueprint.
  • Create a VCam Widget with a button and logic.
  • Create a HUD to manage the Connection Point.

Add Connection Points to a Modifier

To add Connection Points to a Modifier Blueprint:

  1. Open the VCM_LookAt Modifier Blueprint.

  2. Click Class Defaults from the Blueprint toolbar.

    Click Class Defaults in the Blueprint toolbar.

  3. In the Details panel under the VCam Connection Points category, expand Connection Points and click the Add (+) icon to add a new element. Name the element "ToggleActivation".

    Adding a Toggle Activation element under Connection Points.

  4. Expand the properties for the ToggleActivation element and assign IA_ToggleActivation Input Action Asset to the Associated Action assignment slot.

    Selecting the Toggle Activation input action as the Associated Action.
  5. Compile and Save.

Create a VCam Widget and Initial Setup

In this section, you'll create the buttons that'll be used to toggle the virtual camera's object tracking on and off,using a VCam Widget asset. Unlike UMG Widgets, VCam Widgets differ in their ability to accept input and define connections to Modifier Connection Points.

To create a VCam Widget:

  1. In the Content Browser, click Add (+) > VCam and add a VCam Widget Asset. Name the widget VCW_ConnectionButton.

    Creating a VCam Widget via the Content Browser Add options.

    A pop up window prompts you for an Input Mapping Context. You can click Skip to proceed with opening the Blueprint.
  2. Open the VCW_ConnectionButton Blueprint.

  3. Select the Library panel and under the Common category, drag a Button into the designer graph.

    Adding a button from the library.

  4. In the Hierarchy panel, rename the Button to "Button".

    Renaming the button.

  5. In the top-right of the VCam Widget Blueprint, click on Graph to open the editing mode for Blueprint scripting.

    Go to the Graph mode in the VCam Widget Blueprint.
  6. Select Class Defaults from the Blueprint toolbar.

  7. In the Details panel, navigate to the VCam Connection category, expand Connection, and click the Add (+) icon to add a new element. Name the element "Button".

    Adding a connection to the VCam Widget Blueprint.

  8. Expand the properties for the Button connection element and set the following properties:

    Configure the Button Connection settings.
    • Requires Input Action should be checked.
    • Action Type should be set to Digital (bool).
  9. Compile and Save.

You now have a VCam Widget Named VCW_ConnectionButton with a Button widget.

Create VCam Widget Blueprint Logic

With the VCam Widget button setup in the previous section, you can add some scripted logic to the VCam Widget Blueprint to control how the button widget interacts with the Modifier Blueprint (VCM_LookAt).

To add the VCam Widget's Blueprint logic:

  1. In the Graph mode, go to My Blueprint > Variables, and select the Button variable.

  2. In the Details panel and expand the Events category, and click the Add (+) button next to On Clicked to add one to the graph.

    Adding an On Clicked event to the Blueprint graph.
  3. Right-click in the Event Graph and add a Get Connections variable from the VCam Connections category.
  4. Drag off the Get Connections variable and add a Find node. Set the Key Name text field input to be "Button" — matching the name of your Connection created earlier.
  5. Drag off the output pin of the Find node's Blue pin and add a Get Connected Modifier node.
  6. Drag off the Return Value of the Get Connected Modifier node and add a Get Owning VCam Component node.
  7. Drag off the Return Value of the Get Owning VCam Component node and add an Inject Input for Action node.
  8. On the Inject Input for Action node, do the following:
    • Right-click the Raw Value input and select Split Struct Pin to show individual inputs for X, Y, and Z values.
    • Set the Raw Value X to 1. This ensures when the button is pressed, your Input Action receives a value matching True, which mimics a hardware button's down press.
    • Set the dropdown selection for Raw Value Type to Digital (bool).
  9. Drag off the Find node's Blue pin and add a Get Connected Input Action node.
  10. Drag off the Return Value of the Get Connected Input Action node, and connect it to the Action input of the Inject Input for Action node.
  11. Compile and Save.

Once completed, your VCW_ConnectionButton VCam Widget Blueprint graph should look similar to this:

Copy and paste the Blueprint code above directly into your VCM_LookAt Modifier to recreate the graph above in your own project.

Create a HUD to Manage the Connection

In this section, you'll create a new VCam Widget that uses the Button VCam Widget you created in the previous section. This widget is used to display a clickable button that sets the toggle state of the virtual camera's object tracking behavior set up in the Modifier Blueprint created earlier in this guide.

To create a HUD:

  1. In the Content Browser, click Add (+) > VCam and add a VCam Widget Asset. Name the widget VCW_ConnectionHUD.

    Creating a VCam Widget via the Content Browser Add options.

    A pop up window prompts you for an Input Mapping Context. You can click Skip to proceed with opening the Blueprint.
  2. Open VCW_ConnectionHUD.

  3. In the Library panel in the Search Box, type in "VCW_ConnectionButton". You should see the VCam Widget of the same name that you created in the Create a VCam Widget section.

    Searching the library to add the VCW_ConnectionButton Blueprint.
  4. Drag the VCW_ConnectionButton from the Library panel into the Hierarchy panel.

  5. Right-click on the VCW_ConnectionButton widget in the Hierarchy panel and go to Wrap With and add a Canvas Panel from the breakout list.

    Wrap the button with a Canvas Panel.

    Wrapping with the Canvas Panel is used to prevent the HUD from being a button that takes up the entirety of the screen.

  6. In the Details panel under the VCam Connections category, expand Connection Points > Button.

    Expanding the button connection properties.

  7. Check the box next to Manually Configure Connection. A new expandable category called Connection Target Settings appears.

    Enabling manually configuring connection property.

  8. Expand Connection Target Settings and set the following:

    Set the Connection Target Settings.
    • Set the Target Modifier Name to "LookAt".
    • Set the Target Connection Point to "ToggleActivation".
  9. Save and Compile.

You should now have a VCam Widget Blueprint for the HUD to display your Button VCam Widget with its logic to set its state.

VCam Connection HUD Blueprint graph.

By default, when you add the Button and wrap it to the Canvas Panel, it is placed in the top-leftmost corner of the screen. You can choose to move this button in the VCam Widget's Designer by clicking and dragging it to another part of the canvas to display it in a different part of the screen. Also, if you want this button's functionality to be clearer, you can add text to it in the Hierarchy panel.

The result of the HUD when in-game.

Set the HUD Blueprint on the VCam Component

With the HUD VCam Widget Blueprint set up, your next step is to apply it to the VCam Component to be displayed on the screen as an element of the Output Providers.

To apply the HUD VCam Widget to a VCam Component:

  1. Select your Virtual Camera Actor in the level.
  2. In the Details panel, select the VCam Component from the components hierarchy.

  3. In the Details panel under the Output Provider section, use the Output Provider Element you created in the Initial Setup of an Output Provider section or add one now.

    Using an Output Provider with your VCam Component.

    This demonstration uses the Pixel Streaming Output Provider.

  4. Expand the Output Provider element and set the following:

    Configure the Output Provider settings.
    • Use the dropdown selection for UMG Overlay to assign your VCW_ConnectionHUD VCam Widget.
    • Check the box next to Is Active.

    If this is already checked, uncheck and check it again to manually refresh the output provider.

Once you've assigned the HUD to the VCam Actor, you can click the button in the viewport to toggle object tracking on and off. In this example, the sphere is set up with a InterpToMovement and moves back and forth when using Simulate or Play-in-Editor modes. This makes it easier to test the virtual camera's object tracking when toggling it off and on again.

Virtual Camera Customization Through Connections and Blueprint Interfaces

This section of the guide is optional.

This section of the guide demonstrates how you can customize your virtual camera HUD further using Connections and Blueprint Interfaces to change the button color according to the state of the Modifier. This is useful for features where you want to reuse a single-button VCam Widget for different purposes, like VCW_ConnectionButton that was created earlier in this guide.

Create a Blueprint Interface Asset

In this section, you'll create a Blueprint Interface that is used to connect to your Modifier Blueprint.

To create a Blueprint Interface:

  1. In the Content Browser, click Add (+) > Blueprint and add a Blueprint Interface Asset. Name the interface BPI_ConnectionButton.
  2. Open BPI_ConnectionButton.

  3. In the My Blueprint panel under the Functions category, rename NewFunction to "GetButtonColor".

    Creating a new function.

  4. In the Details panel, locate the Inputs category, and click the Add (+) icon to add a new parameter. Set its type to Name and name it "ConnectionPoint".

    Adding a connection point.

  5. In the Outputs category, click the Add (+) icon to add two parameters:

    Adding parameters.
    • Name the first parameter "Color", and set its Type to Linear Color.
    • Name the second parameter "Success", and set its Type to Boolean.
  6. Compile and Save the Blueprint.

Connect Modifier Blueprint to Interface Blueprint

In this section, you'll set up the VCM_LookAt Modifier Blueprint to connect to the BPI_ConnectionButton Blueprint Interface created in the previous section.

To set up the connection to the Blueprint Interface:

  1. In the Content Browser, open the VCM_LookAt Modifier Blueprint created in the Create a Modifier Blueprint section of this page.
  2. Select Class Settings from the Blueprint toolbar.

  3. In the Details panel, locate the Interfaces category, and use the dropdown selection for Implemented Interfaces to select the BPI_ConnectionButton Blueprint Interface.

    Adding the blueprint interface to the modifier blueprint.
  4. Compile and Save.

Set Up the Interface Blueprint Logic

With your Blueprint Interface connection implemented with the VCam Modifier, you can add some logic to VCM_LookAt Modifier Blueprint to define which color the button sends when toggled on and off.

To connect your button:

  1. In the VCM_LookAt Blueprint, go to the My Blueprint panel. Under the Interfaces category, double-click Get Button Color to open its own graph tab.

    Opening the Get Button Color event graph.
  2. In the Get Button Color graph, drag off the Connection Point pin and add a Switch on Connection Points node.
  3. Break the wire between the Get Button Color node and the Return Node by holding ALT and Left Mouse Click the wire.
  4. Drag off the Get Button Color node and connect it to the Switch on Connection Points node.
  5. Drag off the Default execution pin of the Switch on Connection Points and connect it to the Return Node. Move the Return Node down and out of the way for the next step.
  6. Drag off the Toggle Activation execution pin of the Switch on Connection Points node and add a Return Node.
  7. Check the box next to Success on the Return Node.
  8. In the My Blueprint panel, locate the Variables category, and drag the ShouldLookAt variable into the graph and select Get ShouldLookAt from the list.
  9. Drag off the Get ShouldLookAt node and add a Select Color node.
  10. Drag off the Return Value output pin of the Select Color node and connect it to the Color pin of the Return Node coming from the Toggle Activation execution of the Switch on Connection Points node.

  11. On the Set Color node, click the box next to A and B to open the color picker and set a color for each.

    Setting a color on the Set Color node using the color picker.
  12. Compile and Save.

Your Get Button Color graph should look similar to this:

Copy and paste the Blueprint code above directly into your VCM_LookAt Modifier to recreate the graph above in your own project.

Set Up the Modifier Blueprint Logic

In this section, you'll set up how the widget requests, parses, and applies the information configured in the previous section.

To define the rules:

  1. Open the VCW_ConnectionButton VCam Widget created in the Create a VCam Widget and Initial Setup section of this page.

  2. Click the Graph button to switch to graph editing mode.

    Switching to the Graph mode in the ConnectionButton Blueprint.
  3. In the Blueprint toolbar, click on Class Defaults.
  4. In the Details panel, locate the VCam Connections category, expand Connections, then expand Button.

  5. Click the Add (+) icon next to Required Interfaces, and select the BPI_ConnectionButton Blueprint Interface from the list.

    Adding the required interfaces.

    You can use either Required Interfaces or Optional Interfaces when assigning the Blueprint Interface to this VCam Widget Blueprint. Assigning it to the Required Interfaces makes it mandatory for your Modifier Blueprint to have implemented your Blueprint Interface in order for the connection to succeed. If you choose Optional Interfaces, the connection can succeed regardless of your Modifier Blueprint having implemented the Blueprint Interface.
  6. Right-click in the Event Graph and add a Get Connections variable from the VCam Connections category.
  7. Drag off the Get Connections node and add a Find node.
  8. Drag off the blue pin of the Find node and add a Get Connected Modifier node.
  9. Drag off the Return Value of the Get Connected Modifier node and add an Is Valid node.
  10. Drag off the Return Value of the Get Connected Modifier node and add a Get Button Color (Message) node.
  11. Drag off the blue pin of the Find node and add a Get Connection Point Name node.
  12. Drag off the Return Value of the Get Connection Point Name and connect it to the Connection Point input of the Get Button Color node.
  13. Drag off the Event Tick node and connect it to the Exec input of the Is Valid node.
  14. Drag off the Is Valid execution pin of the Is Valid node and connect it to the Get Button Color node.
  15. Drag off the Get Button Color execution pin and add a Branch node.
  16. Drag off the Success pin of the Get Button Color node and connect it to the Condition pin of the Branch node.
  17. In the My Blueprint panel under the Variables category, drag a Button variable into the graph and select Get Button from the list.
  18. Drag off the Button node and add a Set Background Color node.
  19. Drag off the True pin of the Branch node and connect it to the input on the Set Background Color node.
  20. Drag off the Color pin of the Get Button Color node and connect it to the In Background Color pin of the Set Background Color node.
  21. Compile and Save.
