Probes resolution

Specifies the resolution value for Reflection Probes in the Viewport, and when exporting images, videos, panoramas, and Local Presentations.

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

The default value for Viewport and Export is 256.

Options: 64, 128, 256, 512, 1024

If you are using Reflection Probes to create a mirror, we recommend selecting 1024.

Skydome resolution

Defines the resolution of Sky Light HDRIs and Backdrop HDRIs in the Viewport and when exporting images, videos, panoramas, and Local Presentations.

The default value for Viewport and Export is Medium.

Options: Low, Medium, High

Grass fading

Specifies at what distance from the camera grass starts to appear in the Viewport.

This pertains only to grass from the Library > Vegetation and landscape > Grass and flowers and Detail grasses categories added with the Vegetation Painter or Vegetation Scatter tools.

The default value is Medium.

Near: Grass can be seen at a distance of 15 meters from the camera.

Medium: Grass can be seen at a distance of 30 meters from the camera.

Far: Grass can be seen at a distance of 50 meters from the camera.

Selecting Near can help to improve performance and the frame rate in the Viewport.

Custom paths

Specifies the location where User Library assets, and downloaded Quixel Megascans, Twinmotion, and Sketchfab assets are saved on your computer.

By default, the files are saved in the UserLibrary, QuixelCloudLibrary, TwinmotionCloudLibrary, and SketchfabCloudLibrary folders in the following location:

  • Windows: C:\Users\[username]\Documents\Twinmotion[version]\[folder name]

  • MacOS: HD:Users:[username]:Documents:Twinmotion[version]:[folder name]

Direct Link

Specifies the location of the DirectLinkTextures folder.

When 3D models are imported into Twinmotion with the Datasmith Direct Link workflow, imported textures are saved in this folder. For more information, refer to The DirectLinkTextures folder.

By default, the files are saved in the following location:

  • Windows: C:\Users\[username]\Documents\Twinmotion[version]\DirectLinkTextures

  • MacOS: HD:Users:[username]:Documents:Twinmotion[version]:DirectLinkTextures

Angle snap

Specifies the increments in degrees by which objects are rotated when using the Rotate tool.

The default value is five degrees ()

Save

Enables or disables the autosave feature, and specifies the autosave settings and the location where files are saved.

Interval: Sets the time interval between autosaves. By default, the value is 15 minutes.

Number: Specifies the number of files to save. When the number is reached, newly saved files overwrite existing files. By default, the value is 3.

Path: Specifies the location where files are saved. By default, files are saved in the following location:

  • Windows: C:\Users\[username]\Documents\Twinmotion[version]\AutoBackups

  • MacOS: HD:Users:[username]:Documents:Twinmotion[version]:AutoBackups

Export

Defines the following export settings for media:

Update reflections: Updates the Reflector Probe reflections at each frame. This can be useful when creating videos, to ensure that reflections are accurate when moving around a scene. Selecting this option can increase rendering time.

Warming up: Updates particles before media is exported.

Smog / haze quality: Improves the quality of Volumetric Fog.

Vsync

Select the Activate check box to limit the frame rate of the scene in the Viewport to match the refresh rate of the screen. This can help to improve performance and lower power consumption.

For more information about the frame rate in Twinmotion, refer to FPS in Statistics.

Point Cloud

Select the High quality export checkbox to improve the resolution of Point Clouds in exported images, videos, panoramas, and Presentations.

Selecting this option can increase Video Random-Access Memory (VRAM) usage and increase processing times.

VR

When viewing Twinmotion in Virtual Reality (VR) mode, this setting determines whether the right or left hand controls the VR menu.

Options: Right, Left

Quality

The settings in the Quality tab determine the quality of the resolution and of certain rendering features on both your computer screen (Desktop) and in VR mode.

These settings have an effect on the viewing quality in the Viewport only. They do not affect the quality of exported images, videos, panoramas, or Presentations. Exported media is always exported in Ultra quality, regardless of the settings in the Quality tab.

The quality levels you can select are : Low (25%), Medium (50%), High (75%), and Ultra (100%). Each level corresponds to a percentage of screen resolution, which is arrived at by using a resolution-based scaling technique called Screen Percentage.

By default, Auto is selected, which means that Twinmotion automatically measures the performance of your computer, and adapts the quality of the resolution and rendering features accordingly to provide smooth navigation inside Twinmotion.

You can, however, select Custom quality settings for each rendering feature. Higher quality settings increase the frames per second (fps) in Twinmotion.

Quality Settings

The table below provides a description of the quality level settings for each rendering feature. The settings are listed in descending order by which they affect Graphics Processing Unit (GPU) performance.

Setting

Description

Dynamic resolution

Adapts the Viewport resolution dynamically to improve performance and maintain an optimal frame rate.

The resolution is adjusted based on the complexity of the scene and GPU usage.

This option is activated once the frame rate value in Activation threshold (in FPS) is reached.

DynamicResolution (in FPS)

If the Dynamic resolution option is selected, this setting specifies the frame rate threshold, in frames per second (FPS), at which Dynamic resolution is activated.

The default value is 25 fps.

VR Dynamic Quality (VR mode only)

If this option is selected, Twinmotion dynamically adjusts the quality settings in an attempt to reach the target rendering frame rate of 45 fps (90 Hz/2) in the Viewport.

A rendering frame rate of 45 fps can minimize VR motion sickness.

Use VR headset threshold (VR mode only)

If this option is selected, Twinmotion attempts to match the target rendering frame rate in the Viewport to the refresh rate of the VR headset.

Matching the rendering frame rate in the Viewport to the refresh rate of the VR headset can help to minimize VR motion sickness.

Due to certain limitations, the VR headset refresh rate is currently set to 45 fps.

Activation threshold (in FPS) (VR mode only)

If the Use VR headset threshold option is not selected, this setting specifies the frame rate threshold, in frames per second (FPS), at which VR Dynamic Quality is activated.

Specifies whether sounds that are added to a scene from the Library > Objects > Sounds category can be heard in Twinmotion and in exported Local and Cloud Presentations.

Note that for the sound to be heard in Twinmotion and in Presentations, the Audio setting of the sound must be enabled (On).

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.

Footstep sounds can be enabled or disabled in the All sounds setting.

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