For complete details on the recommended hardware and software specifications for the latest official release of Twinmotion, please refer to Hardware and Software Specifications.       

What’s New

Photo Match Tools

A new set of photo match tools that provide seamless integration of 3D models into images has been added to the Ambience panel. You can find it in the Camera tab, under the new Backplate category.

With the photo match tools, you can load a background image and project shadows from your 3D scene onto it.

In Media mode, a new Match perspective tool provides you with an easy way to set the camera position and focal length by identifying the vanishing points in your backplate.

For more information, see Backplate and Match Perspective in the Ambience Settings documentation.

Known Issues and Limitations

• The Match perspective tool does not work on backplate images already corrected for perspective, such as architectural shots with straightened vertical lines, because no vanishing points remain.

• Enabling the Shadow catcher is resource-intensive and will significantly reduce FPS, as the image must be rendered three times to composite the shadow onto the backplate.

• Orthographic views are not supported when the Backplate feature is enabled.

• The Shadow catcher and Match perspective tools are not supported when the viewport is in Full screen mode.

Autosoft Edge

Discover Autosoft edge, a new feature that makes your renders more realistic by automatically smoothing out sharp edges. It works in both the Path tracer and Lumen rendering modes, and is a simple way to improve the quality of your visualizations and achieve a higher level of realism without the need for any technical expertise.

The Autosoft edge feature is accessible for imported meshes in the Properties panel. It is currently enabled for most Twinmotion assets, but works only on a subset of them. 

Lighting Channels

With the new Lighting channels feature, you can fine-tune the lighting in your scene by precisely controlling which elements of the scene your physical lights affect. Only objects and lights assigned to the same channel will interact.

The Lighting channels feature can be accessed in the Properties panel for objects and physical lights.

For more information, see the Lighting Channels documentation.

Limitation

Lighting channels are not currently supported in the Lumen rendering mode when either Reflections only or Full are used for the Ray lighting mode. In these modes, lights will still appear in the reflections and global illumination of meshes, even if the physical lights and objects do not share the same channel.

Camera Barrel Distortion

With the new Barrel distortion slider,  you can recreate the natural barrel distortion that occurs with real-world lenses, especially wide-angle ones. The barrel distortion effect subtly curves straight lines near the edges of the frame.

You can find the Barrel distortion slider in the Camera tab of the Ambience panel, under Lens > Details.

Anamorphic Oval and Petzval Bokeh

Additional options to recreate real-world lens bokeh based on Anamorphic oval and Petzval lenses have been added to the Depth of field category in the Camera tab of the Ambience panel.

Auto Focus

A new Auto focus option for Depth of field has been added to the Camera settings. With this option, the focal length is automatically set based on the center of the screen.

Improvements to the Particle Systems

The particle systems in the Library > Objects > VFX category have been completely revamped to enhance optimization and visual quality.

This update introduces newly reworked fire, fog, smoke, and water jet effects, along with new customizable parameters to tailor the effects to your needs.

European Tree Pack

A collection of 30 photorealistic European trees has been added to the Twinmotion Library. It offers a rich diversity of shapes and sizes, providing you with more flexibility to enhance and enrich your scenes.

Every tree species is offered in 3 variations, enabling you to achieve a more natural look when used in the same biome.

Datasmith Plugin Notification System

A new Datasmith Exporter plugin notification system has been added to the Home panel under Plugins. You will now be notified if there is a Datasmith plugin available to download. The system will detect which 3D modeling softwares and version are installed on your system, and will offer a download link for the Datasmith Exporter plugin for that software. 

Additionally,  notifications will appear in the Home panel when there is an available update for an already installed Datasmith Exporter plugin. A red dot will appear on the Plugins tab in the Home panel, and on the Home panel icon in Twinmotion, to indicate these notifications.

Interchange Import for the FBX and OBJ File Formats

We are gradually shifting away from our legacy importing pipeline towards a proprietary importing pipeline called Interchange. The benefits of this importing method are a better control on the fidelity of initial imports, as well as on reimports with objects in the scene that have undergone overrides. The first two file formats we are introducing Interchange with are FBX and OBJ imports. 

Additionally, we are deprecating the function Collapse by material as its original main function was to optimize the file on import. With new features such as Lumen and Path tracer,  this function has caused issues, and due to limitations are not resolvable. There are many workarounds to have the same control and optimization as Collapse by material. Users can use Collapse all and still apply materials to identical materials with the Replace material option for material application. Please review the list of known bugs for reference.

We added a new Use legacy importer option in the Preferences panel under Import in the Settings tab. When the checkbox is selected, all imports for the .fbx and .obj file types fall back to the legacy importing pipeline. Keep in mind that this checkbox will remain selected when you close and reopen a Twinmotion project or window. You will need to manually deselect the checkbox to return to the Twinmotion Interchange importing pipeline. This feature is a temporary preference option designed to help users who are encountering issues with the Interchange import pipeline.

Deprecations

• Collapse by material

New features with Interchange for .fbx and .obj file types  

• Reset transform on selected 

• Reset material on selected 

• Reimport deleted objects

Unreal Engine Landscape Integration

We recently revamped Twinmotion’s terrain system by adopting Unreal Engine's native landscape system. There is no additional feature in the user interface, but this update fixes several Lumen-related issues, ensures full Lumen support, and enables terrains to contribute to global illumination for more realistic lighting.

This integration also prepares Twinmotion for the following future Unreal Engine developments: more efficient handling of large scenes (work partitioning and streaming), support for large open worlds, better consistency with Procedural Content Generation (PCG), and stronger alignment with ray-traced rendering workflows.

Xcode Requirement on macOS

To run Twinmotion 2026.1 on macOS, Apple requires that Xcode be installed on your computer.

Xcode is a free Apple application used by macOS to run certain software components.

If Xcode is not installed on your computer, a message will appear the first time you attempt to open Twinmotion to let you know it is missing. To open Twinmotion, you will need to install Xcode, and open it at least once to accept the licensing terms and to install additional software.

What to expect the first time you launch Twinmotion

1. Install Xcode

   1. When you launch Twinmotion 2026.1 for the first time, a message appears saying that Xcode is missing.

      

   2. Click Yes to automatically open the Mac App Store.  

   3. Sign in to your Apple Account using your Apple ID.

   4. Click the Download icon to install Xcode.

      

      The download and installation may take some time, as Xcode is a large application.

2. Open Xcode once

   1. When the installation is complete, you must open Xcode at least once to accept the licensing terms and install some required additional components.

   2. Close Xcode (optional).

   If you do not launch Xcode at least once and accept the Xcode license, you may see a message related to an Xcode licensing error when you attempt to launch Twinmotion. If this happens, click Yes to launch Xcode and to accept the licensing terms and install the required additional components. You do not need to install the optional components.

   

3. Allow Twinmotion to open (macOS security)

   When you launch Twinmotion again, you may see a message saying Twinmotion cannot be opened. This is a standard macOS security message.

   

   If you see this message, click Done, and do the following:

   1. Open System Settings. 

   2. Go to Privacy & Security, and scroll down to the Security section.  

   3. In the Security section, you will see a message saying Twinmotion was blocked to protect your Mac. Click Open Anyway.

   4. Confirm by clicking Open Anyway again when prompted.

      

4. Reset Xcode State (will rarely happen)

   In some rare cases, you may see a message about an Xcode configuration error. This is usually due to an Xcode update, or can occur if you have multiple Xcode versions installed on the same machine. If you see this message, do as follows:

   1. Click Yes to let Twinmotion reset the Xcode state for you.

   2. In the system prompt that appears, enter your macOS user name and password.

      

      Resetting Xcode is done via a very simple OSAScript (Open Scripting Architecture) that requires elevated privileges to run. 

   3. A message may appear asking you to select an Xcode version. If you see this message, choose macOS 26.2.

5. Final step

   Launch Twinmotion again. Twinmotion should now open normally.

Persistent File Location

Starting with Twinmotion 2026.1, the cloud-based content you download in Twinmotion is stored in a persistent file folder structure. This ensures that any content you download and any assets you copy to the User library can be accessed immediately when you install a new version of Twinmotion. The cloud-based content includes: the Twinmotion Library packs, the Twinmotion native assets, the Quixel Megascans and Sketchfab library assets, and the Twinmotion visualization templates.

By default, the downloaded content is stored in the following location:

• Windows: C:\Users\UserName\AppData\Local\Twinmotion

• MacOS: MacintoshHD/User/UserName/Library/Caches/com.epicgames.TwinmotionCookedEditor/Twinmotion

The first time you open Twinmotion version 2026.1, the Twinmotion library setup window automatically appears. You will be prompted to enter a default location for the Twinmotion cloud content you download on your computer. We recommend using the suggested default location, but if you prefer, you can select another location.

If you have a previous version of Twinmotion installed, you will also be prompted to copy the content from your previous Twinmotion version into the new persistent folder structure. This content includes any assets and templates you downloaded, and any assets you copied to the User library. Copying the content does not delete your original files. If you have more than one previous Twinmotion version installed, you will be asked to select a version. You can migrate the contents of more than one Twinmotion version into the new persistent file folder structure, but you must do so one version at a time.

If you do not want to copy your existing content or enter a default location for Twinmotion cloud content the first time you open 2026.1, you can do it later by selecting Library transfer in the Edit menu.

For more information, see Persistent File Location in the Working with Cloud Content documentation.

Better Library Support

The library items from previous versions that were not supported in 2025.2 are now supported and visible in the Library panel.

The User library now supports instant updates. If a User library that is shared among many users is updated (for example, if an asset or a folder is added or deleted), it will be instantly updated for all users of the shared User library.

Bake Scale on Imports

We have updated object scaling on import to resolve many issues caused by inherited transform scales.

When importing, the transform scale in Twinmotion will now always be set to 100%, 100%, 100%. Any scaling from your DCC (such as SketchUp, Rhino3D or 3ds Max) is applied directly to the geometry, not the transform. This applies to all objects, including instanced objects.

This change eliminates problems associated with negative and non-uniform scaling, greatly improving rendering precision and overall stability. Your imported assets will look correct while maintaining clean transform data.

Properties Panel Revamp for Imported Animated Files

The Properties panel settings for imported animated files have been completely reworked. Additional controls have been added to better align animated files with the workflow of other animated assets, such as the animators.

Configuration Improvements

A new option has been added to capture the camera position for an entire configuration.

The shape of triggers and of states can now be customized and switched from circle to rounded corner or square.

Certain user interface changes have been done to simplify the overall experience.

Substrate Materials

Preparatory steps have been taken to transition to Substrate materials in the future. Users should not experience any important visual differences.

Tessellation Controls for Selected *.wire Objects

You can now refine or simplify the mesh tessellation of imported *.wire objects directly from the Properties panel in Twinmotion. This brings the same tessellation controls available at import time into the scene workflow, allowing you to adjust geometry without reimporting the file.

After selecting a *.wire object in the scene, the Tessellation section provides the following controls which are all similar to the controls the user will get in the Import window.

• Tessellation preset and Preset Manager

• Chord tolerance

• Geometric tolerance

• Use max edge (checkbox)

• Max edge length

• Normal tolerance

• Stitching tolerance

• Stitching technique (None, Heal, Sew)
