Use the Ambience panel to create and customize ambience settings for your Twinmotion scenes and media assets. The ambience settings are in the following four tabs:
You can open the Ambience panel in the following two ways:
In the Media dock, select an image, video, sequence, or panorama.
In the Scene panel, click Ambience.
By default, certain measurement unit values in the Twinmotion user interface are shown in meters (m); these values are also shown in meters in the documentation. You can, however, switch the unit type displayed in the user interface to centimeters (cm), inches (in), or feet (ft). To do this, press Ctrl+P to open the Preferences panel, and click Unit system.
Certain maximum values for settings can be overridden. For example, the maximum value that can be attained by moving the slider for the Path tracer > Samples per pixel setting is 8192. However, you can override this value by manually entering a value. When the maximum value of a setting can be overridden, it is marked by an asterisk ( * ) in the tables below.
Env (Environment)
Env Preset
The Env tab contains high-quality customizable Env presets that feature carefully designed lighting and environments. The current presets include the following environments: Sunrise glow, Sunny coast, Golden hour, Rainy day, Fogbound, Mars horizon, and Lunar surface.
You can also design your own environments and save them as Personal presets. By default, personal presets are stored in the following location:
Windows:
C:\Users\\[username]\Documents\Twinmotion[version]\UserLibrary\_LocalPresets
MacOS: HD:
Users:[username]:Documents:Twinmotion[version]:UserLibrary\_LocalPresets
Personal presets you create are stored locally on your computer and it is not currently possible to share them easily between users. When opening a scene that contains personal presets on another computer, the preset settings are retained but the names revert to "Custom".
Dynamic sky
The default lighting environment in Twinmotion is provided by the Twinmotion Dynamic sky system. When Dynamic sky is used, lighting is based on the Sun, Sky, and Clouds settings.
Sun
Setting | Description |
---|---|
Time of day | Sets the time of day of the scene and updates the lighting in the scene accordingly. You can select a 12-hour or 24-hour clock in the Preferences panel under Settings > Timestamp. |

Stars intensity | Sets the intensity of stars during night scenes. Options: 0.0 to 3.00 This setting is available only when the Path tracer rendering mode is not in use. |
Clouds
In the Dynamic sky environment, you can use 2D clouds or Volumetric clouds:
2D clouds are 2D textures applied to a distant, invisible sphere. They are less memory intensive, but also less realistic than volumetric clouds.
Volumetric clouds are true 3D volumetric representations of clouds. They can be animated, cast shadows, and are highly customizable. They provide much greater realism than 2D clouds, but this comes at a significantly higher performance cost.
Limitations
Due to hardware limitations, the quality of volumetric clouds is downgraded in Path tracer rendering mode when using AMD graphics cards.
For performance optimization, when volumetric clouds interact with geometry, no fading occurs in the viewport, and artifacts may appear. This limitation does not affect the media you export from Twinmotion.
In Real time rendering mode, especially at sunrise and sunset, some imprecision in the cast shadows may be observed, resulting in visual differences between the viewport and exports.
Setting | Description |
---|---|
Cloud slider | Adds 2D or Volumetric clouds to the sky. The settings go from clear sky to full cloud coverage. |
Clouds preset | Select one of the customizable volumetric cloud presets (Small or Large cumulus, Cirrus, Altocumulus, Cumulonimbus, Stratus, or Nimbostratus) or create your own custom volumetric clouds and save them as Personal presets by clicking the Add icon. Limitations
|
Random seed | Clicking the Random seed icon or manually entering a value generates variants of the selected volumetric cloud type. Using the same seed value creates the same type of cloud variant. |
Height | Sets the height of volumetric clouds relative to the starting ground. Options: 250 m to 4000 m |
Appearance | |
Scale | Controls the size of volumetric clouds. Lower values produce several smaller clouds, and higher values produce larger masses of clouds. Options: 0.00 to 1.00 |

HDRI
High Dynamic Range Images (HDRIs) consist of sky and backdrop environments that provide ready-made Skies, as well as Indoor, Outdoor, and Studio environments for your scenes.
When an HDRI environment is used, you can use a Skydome or a Backdrop, and lighting and reflections are based on the information contained in the HDRI.
The HDRI environments category in the Twinmotion Library contains several ready-made HDRIs. For more information, see "HDRI Environments" in the "Twinmotion Assets in the Library" documentation.
HDRI environment
Setting | Description |
---|---|
Skydome | Provides lighting using Skydome HDRIs, which are spherical domes onto which HDRIs are projected (UV mapped). When Skydomes are added to a scene, they generate lighting and reflections based on the information in the HDRI. Skydomes can be rotated but they cannot be moved or scaled. |
Backdrop | Provides lighting using Backdrop HDRIs, which are hemispherical domes onto which HDRIs are projected (UV mapped). Backdrops provide a background for your scene, but they also generate lighting and reflections based on the information in the HDRI. Backdrops can be rotated and scaled, and the horizontal and vertical UV placement of the HDRI on the dome can be modified. They also have a ground plane that can receive shadows and supports physics; objects can be placed on the ground plane. |
Preview | Shows a preview image of the Skydome or Backdrop. To open a menu where you can view a larger preview, manage Skydomes and Backdrops, and automatically open the Library to the HDRI category, click the ellipsis (...) that appears when you hover over the image. |
Intensity | Controls the intensity of light emitted from the Skydome or Backdrop. Options: 0.00 to 100.00* |
Rotation | Rotates the HDRI Skydome or Backdrop around the scene. If Match HDRI under Directional light is enabled, the directional light changes as the HDRI is rotated. Options: 0° to 360° |
Details | |
HDRI affects lighting | Defines how much lighting the Skydome or Backdrop provides for the scene. When a value of 0.00 is used, the scene is only lit by Directional light. Options: 0.00 to 2.00 This setting is not available in the Path tracer rendering mode. |
Positioning | Sets the position of the Backdrop. You can:
|

Projection offset | Determines the vertical UV projection of the Backdrop on the hemisphere dome on which it is projected. Options: 0.05 m to 100.0 m |
Tilt | Rotates the horizontal UV projection of the Backdrop on the hemisphere dome on which it is projected. Options: -90° to 90° |
Shading | Controls the effect that shadows have on Backdrops. When higher values are selected, shadows have a stronger effect on the Backdrop and are more visible. Lower values (around 0.00) result in shadows being less visible or absent on the Backdrop. Options: 0.00 to 1.00 |
Weather effects | Enables or disables rain or snow cover (added with the Precipitation and / or Season sliders) inside the Backdrop. |
Directional light
Directional light is a light whose source is infinitely far away from the scene. However, unlike the Sun, you can enable Match HDRI which automatically adjusts the intensity, position, and disk size of the directional light according to the information provided in the HDRI.
Match HDRI | When enabled, the Intensity, position (Rotation Z and Rotation X), Color, and disk Size values for the directional light are automatically adjusted according to the selected HDRI. When disabled, these values can be manually adjusted. |
The settings in the following table are not available when Match HDRI is enabled.

Camera
Exposure & WB
Setting | Description |
---|---|
Auto-exposure | Enables or disables automatic exposure, which calculates the overall luminance of the scene and automatically adjusts the exposure to make the scene brighter or darker. Enabling automatic exposure is ideal when moving between interior and exterior scenes, as the exposure is automatically adjusted to mimic the effect of human eyesight when moving between bright and dark environments. Options: On, Off |
White bal. | Sets the white balance using the Kelvin scale. Options: 1500 K to 15,000 K |
Tint | Adjusts the overall color balance of the camera's sensor towards green or magenta. This can help to compensate for color imbalances due to lighting conditions and to ensure a more accurate color reproduction. |
Local exposure | |
Enable | Enables local exposure, which preserves the details in shadows and highlights. This is especially useful in high-dynamic range scenes which have high contrast between light and dark areas. When Local exposure is enabled, details that may not be visible in overly bright or dark areas are enhanced and become more visible. |
Highlights | Reduces highlights to show more details in overexposed areas. Options: 0.00 to 1.00* |
Shadows | Enhances shadows to show more details in dark areas. Options: 0.00 to 1.00* |
Lens
The settings that are marked by an asterisk ( * ) are not available for panoramas.

Focal length* | Sets the focal length of the camera in millimeters, based on the dimensions of a full-frame camera sensor. This setting can only be used on media when Twinmotion is in Media mode. Options: 2 mm to 1500 mm |
Use focal length* | Enables the Focal length setting. |
Details | |
Vignetting* | Sets the percentage of vignetting. Options: 0% to 100% |
Sharpness* | Sets the amount of anti-aliasing. Lower values produce smoother (blurrier) results. Higher values produce sharper results with more aliased edges. Options: 0% to 100% |
Chromatic aberration* | Adds a more realistic effect to renders by simulating the color shifts or distortions that can occur in photos taken with real-world camera lenses. Chromatic aberration is sometimes referred to as color fringing. Options: 0 to 100% |
Intensity* | Defines the intensity of the chromatic aberration effect. Options: 0 to 100% |
Start offset* | Progressively cancels the chromatic aberration effect starting from the center of the viewport or media and expanding outwards toward the edges. In photography, chromatic aberration often occurs at the edges of images. Removing the chromatic aberration effect from the center outwards creates a more natural chromatic aberration effect. Note that the Intensity value must be higher than 0% to see a visible difference. Options: 0.00 to 1.00 |
Align camera | Moves the camera at a perpendicular angle to the surface of an object, making the camera point straight on. |
Parallelism* | Enables or disables parallelism in images. Enabling parallelism makes vertical parallel lines appear vertical regardless of the viewing angle of the camera. Options: On, Off |
Near clipping | This setting determines the distance at which the near clipping plane starts clipping (or hiding) objects that are in front of or nearest to the camera. The near clipping plane cuts objects perpendicularly to the angle of view of the camera, and can be moved forwards or backwards relative to the position of the camera. When viewing a small object in the Viewport at a close range to the camera, part of the object can sometimes get cut off (hidden) by the near clipping plane. Adjusting this value moves the clipping plane, and helps avoid clipping small objects when viewing them at close range. Options: 0.001 m to 1.00* m |
Depth of field

Path tracer | Generates high-quality photorealistic renderings with accurate lighting and global illumination. For information on Path tracer options, refer to Path tracer. |
Real time
Global illumination
Setting | Description |
---|---|
Standard | Approximates global illumination based on Light Propagation Volumes (LPV). This method provides fast results but with less quality and accuracy than Lumen. For information on the settings for Standard global illumination refer to Standard. |
Lumen | Based on ray tracing, Lumen accurately simulates indirect lighting by providing diffuse interreflections with infinite bounces and specular reflections (single and multiple). For information on the settings for Lumen global illumination, refer to Lumen. For information on Lumen and how to use it, refer to Lumen Global Illumination. |
Standard
Setting | Description |
---|---|
GI intensity | When Global illumination is enabled, this setting sets the intensity of global illumination. Options: 0.00 to 1.00 |
GI distance | When Global illumination is enabled, this setting controls the distance from the camera within which global illumination is applied. For example, if the value is set to 400 meters, global illumination is applied only to the first 400 meters from the camera. Options: 0.00 to 1.00 |
Misc. > Reflections - SSR | Enables or disables SSR reflections, which add local reflections to opaque reflective surfaces. Local reflections are created using items in the scene that are visible in the Viewport. To use this setting, the Path tracer must be disabled. Options: 1.00 m to 500.00 m |
Lumen
Setting | Description |
---|---|
Scene detail | The minimum size a surface must be in order to be taken into account by Lumen. Surfaces that are smaller than this value are culled by Lumen, and appear yellow when the Visualize mesh conflicts checkbox is selected. Higher values include more objects but increase RAM usage. Options: 0.0 to 4.0 |
View distance | The view distance from the camera, in meters, in which Lumen has an effect. Selecting a value of 0 (zero) means Lumen has no effect at all on the scene. Options: 0 to 20,971.52 meters |
Lighting update speed | The speed at which Lumen updates real-time global illumination. Lumen uses an iterative process to calculate and propagate global illumination in real time. This setting changes the frequency of the calculations and the speed at which the final lighting solution is updated. Selecting a value of 0 (zero) disables the updates, and a larger value increases the frequency of updates. Note that high values will decrease rendering speed. Options: 0 to 4.0 |
Visualize mesh conflicts | Shows which surfaces were culled by Lumen. Magenta surfaces are areas of meshes too complex to be covered by Lumen, and yellow surfaces exceed the selected values entered in View distance and/or Scene detail. For more information, refer to Visualizing Mesh Conflicts in Using Lumen Global Illumination. |
Lumen reflection settings |
|
Shadows
These settings apply to both Standard and Lumen global illumination.
Setting | Description |
---|---|
Standard | The default shadow mapping method used to provide shadows in Twinmotion. This method has certain limitations (such as faceting on geometric surfaces that are curved and self-shadowing artifacts), but these can be mitigated using the Shadow bias setting. |
Shadow | When Standard shadows are used, this setting controls the distance from the camera up to which shadows on objects are cast. For example, if the value is set to 500 meters, shadows on objects are cast for 500 meters only beginning at the camera. Smaller values provide a shorter range for cast shadows, but produce shadows that are more detailed (higher-resolution). Inversely, higher values provide a longer range, but result in less detailed shadows. Options: 10 m to 5000 m |
Shadow bias | When Standard shadows are used, this setting controls the value of shadow bias. When the value is low, objects feel more grounded along a surface. A higher value helps to reduce unwanted self-shadowing on objects when the surface is lighted at a grazing angle. Options: 0.10 to 1.00 |
Accurate | Provides high-quality shadows using the Virtual Shadow Maps shadowing method. Accurate shadows are more realistic than Standard shadows and render more quickly in the Real time rendering mode (Standard and Lumen). Limitations
|
Sun bias | When Accurate shadows are used, this setting offsets the quality of the shadows to reduce artifacts such as floating or overly sharp shadows, balancing precision and realism. Options: -3.00 to 3.00* |
Lights bias | When Accurate shadows are used, this setting controls the appearance of shadows emanating from any light in the Twinmotion Library on which Shadows are enabled. Higher values produce sharper edges. Options: -3.00 to 3.00* |
Path tracer
Setting | Description |
---|---|
Quality | Sets the Path tracer settings according to the following presets:
|
Samples per pixel | Sets the number of samples per pixel that are used for convergence when path tracing is enabled. Using a higher number of samples decreases image noise, but may increase rendering time. Options: 1 to 8192* |
Max bounces | Sets the maximum number of ray bounces when path tracing is enabled. The number of bounces corresponds to the number of times light is reflected (bounced) on surfaces. Higher values can increase rendering time. Options: 1 to 100 |
Emissive materials | Controls the impact that emissive materials have on bounce lighting in path tracer rendering mode. When enabled, emissive materials influence bounce lighting and contribute to global illumination. You may want to disable this option in certain cases to decrease image noise, for example when an interior scene contains small objects with self-illuminated materials. Options: On, Off |
Denoiser | Enables or disables the image denoiser when path tracing is enabled. Options: On, Off |
Fireflies | Sets the visibility and exposure of small overbright rendering artifacts (fireflies) when path tracing is enabled. Options: -10.00 to 30.00 |
