Twinmotion Preferences

Unit system

Sets the unit system used in the Twinmotion user interface.

By default, Meters are used.

Options:  Millimeters (mm), Centimeters (cm), Meters (m), Feet (ft), Inches (in)

Navigation

• Orbit mode: Specifies the orbit navigation mode for the default camera in the viewport.

  • Around the mouse pointer: The camera orbits around the position of the mouse pointer in the viewport. This is the default orbit mode in Twinmotion.

  • Around a point: The camera orbits around a preselected point in the viewport. You can select the point by double-clicking with the right mouse button in the scene, or by selecting the Orbit point icon in the toolbar and clicking once in the scene. If you do not select a point, the camera orbits around the origin of the XYZ coordinates (0,0,0) of the scene, which is the center of the scene.

  • Around the center of the viewport: The camera orbits around the center of the viewport.

• Orbit around selection: The camera orbits around the object(s) selected in the scene. This option overrides the selected Orbit mode.

• Camera inertia: For smoother navigation, with this setting you can progressively slow down the viewport camera once you have stopped navigating in the scene. When you stop navigating, the movement of the viewport camera progressively slows down in a smooth manner,  according to the percentage selected, until coming to a full stop.

• Use relative mouse: Improves the ability to accurately navigate and drag objects in a scene, especially if you use a pen tablet or use Twinmotion in a remote desktop environment.

Time stamp

Sets how the time of day is displayed in the Time of day option in the View menu, and in Settings > Location > Time of day.

Options: 24H, 12H

Specifies which version of the DirectX technology to use for the DirectX Raytracing (DRX) feature on the Graphics Processing Unit (GPU).

DirectX12 is required to use the Path tracer feature and to enable Lumen global illumination.

By default, DirectX12 is selected if it is supported by the GPU.

Options: DirectX11, DirectX12

Path tracer

Multi-GPU

Select the Multi-GPU checkbox to enable support for multiple GPUs when using the Path tracer.

Sample settings

Specifies the maximum number of samples per pixel and light bounces to use for the Low, Medium, and High presets of the Path tracer.

The default presets are as follows:

Nanite

Defines how Nanite is enabled on imported geometry if you select Enable Nanite in the import options. Once the content is imported into Twinmotion you can modify these settings in the Properties panel.

• Auto: If selected, the appropriate precision used to generate vertex positions on imported geometry is automatically calculated based on the size of the geometry.

  To improve the precision or optimize disk footprint, you can override this by deselecting Auto and choosing a value in Precision.

• Precision: If Auto is deselected, this option defines the precision used to generate vertex positions on imported geometry.

  Options: 0.00122 mm to 64 cm

  By default, 10 mm is selected.

• Preserve area: If selected, any open boundary edges on the triangles of Nanite meshes are expanded.  We recommend selecting this option when you enable Nanite on foliage meshes.

For more information about Nanite, see Optimizing Geometry with Nanite.    

Probes resolution

Specifies the resolution value for Reflection probes in the viewport, and when exporting images, videos, panoramas, or sequences. 

Reflection probes are used in Real time rendering mode to improve interior and exterior reflections, the reflections on glass surfaces, and to create mirrors.

Options: 64, 128, 256, 512, 1024

Skydome resolution

Defines the resolution of Skydomes and Backdrop HDRIs in the viewport and when exporting images, videos, panoramas, or sequences.

Resolution scaling mode

Specifies how Twinmotion scales the resolution in the viewport for the Real time rendering mode. You can choose Temporal super resolution or NVIDIA DLSS super resolution.

• Temporal super resolution: Unreal Engine's native built-in temporal upscaler / super resolution technology. For more information, see Temporal Super Resolution in the Unreal Engine documentation.

• NVIDIA DLSS super resolution: DLSS (Deep Learning Super Sampling) is an AI rendering technology developed by NVIDIA. DLSS is available only if it is supported by the Graphics Processing Unit (GPU) of the computer.

  NVIDIA DLSS super resolution is supported on the following NVIDIA graphics cards:

  • GeForce RTX 20 series (Turing generation) or higher

  • Quadro RTX series (Turing generation) or higher

Profile

When Temporal super resolution is selected as the Resolution scaling mode, this setting defines the quality as well as the upscaling percentage used for resolution scaling.

Ultra quality corresponds to full resolution and gives the maximum quality you can get on your monitor.

Options: Auto, Ultra quality, Quality, Performance

DLSS super resolution  

When NVIDIA DLSS super resolution is selected as the Resolution scaling mode, this setting defines the quality as well as the upscaling percentage used for resolution scaling.

DLAA ultra quality corresponds to full resolution and gives the maximum quality you can get on your monitor.

Options: Auto, DLAA ultra quality, Quality, Balanced, Performance, Ultra Performance

DLSS frame generation (Desktop mode only)

Specifies the number of additional frames generated between the fully GPU rendered frames. To create the additional frames, the DLSS AI-powered technology extrapolates the data from the GPU rendered frames.

When Auto is selected, the number of additional frames generated is managed automatically and adjusted dynamically. Additional frames are generated only if it improves the fps. Generating frames can have a cost, and depending on your current configuration (such as the GPU, the monitor, or the scene you are working in) can lead to a decrease in fps. If this scenario is detected, additional frames are not generated, or the number of generated frames is reduced. 

Options: OFF, Auto, 2X (one extra frame), 3X (two extra frames), 4X (three extra frames)

Upscaling

Specifies the resolution percentage at which frames are rendered in the viewport when in Path tracer rendering mode. The percentage is calculated against the resolution of the final rendered media, which is always exported in Ultra quality. 

Choosing 30%, 50%, or 70% improves performance but decreases the visual quality in the viewport. Choosing 100% gives the maximum visual quality you can get on your monitor but can decrease performance.

Options: 30%, 50%, 70%, 100%

Enable Lumen in VR

Select this checkbox to use Lumen global illumination when using Twinmotion in VR mode.

Streaming quality

Defines the streaming quality when using the VCam feature.

Options: Low, Medium, High, Ultra

Language

Options: English, Deutsch, Español, Français, 한국어, Polski, Português, 中文, 日本語

Interface scale

Sets the scale of user interface text and icons in Twinmotion.

By default, the value is set to 100%.

Options: 75% to 200%

Visual helpers

Shows or hides visual helpers in the viewport. Visual helpers can help you to identify and select the following assets in the viewport:

• All Rotators and Translators (including those associated with the Doors or other animated elements that use them)

• Reflection probes

• Paths

• Painted and scattered objects

• Lights

• Section cubes

Also enables or disables footstep sounds when viewing a scene in Twinmotion or in a Presentation in Pedestrian mode (View menu > Pedestrian mode).

Sending data

Specifies whether you agree to share Twinmotion usage data with Epic Games.

Footstep

When navigating a scene in Twinmotion or in a Local or Cloud Presentation using Pedestrian mode (View menu > Pedestrian mode), the sound of footsteps is heard as you move forward, backwards, to the left, or the right.

This setting specifies the surface on which the footsteps are walking in Footstep volume.

Options: Carpet, Concrete, Glass, Grass, Gravel, Ground, Metal, Snow, Water, Wood  

Footstep volume

Sets the sound volume of footsteps on the surfaces selected in Footstep.
