Rendering Settings

Controls lighting, resolution, and rendering features.

note

These settings affect all users on the currently active branch of the project.

Navigate to the RENDERING section and expand the panel:

Here is a breakdown of the available settings:

Environment

Setting	Description
Ambient Color	The color of the scene's ambient light, specified in sRGB color space.
Skybox	A cubemap asset rendered behind your 3D scene. Also used as the default environment map for physical materials when prefiltered.
Type	Select the projection used to render the skybox cubemap: Infinite: Rendered at infinity Box: Mapped to a box mesh Dome: Mapped to a hemispherical dome
Mesh Position / Rotation / Scale	The position, rotation and scale of the sky mesh.
Center	The relative normalized offset of the sky from the ground.
Intensity	The skybox intensity, used to match exposure levels.
Rotation	Rotation of the skybox.
Mip	Mip level of the prefiltered skybox. Higher values select lower-resolution, more blurred mips.

Clustered Lighting

Setting	Description
Clustered Lighting	Enable clustered lighting.
Cells (X, Y, Z)	Number of cells per world-space axis used to subdivide the space containing lights.
Max Lights Per Cell	Maximum number of lights a cell can store.
Max Lights	Maximum number of clustered lights visible in a frame. Keep this as low as the scene allows; values above 255 use a larger light-index texture.
Cookie Atlas Resolution	Resolution of the atlas texture storing all non-directional cookie textures.
Cookies Enabled	Clustered lights support cookies.
Shadows Enabled	Clustered lights support shadows.
Shadow Atlas Resolution	Resolution of the atlas texture storing all non-directional shadow textures.
Shadow Type	The type of shadow filtering used by all shadows.
Area Lights Enabled	Clustered lights support area lights.

Gaussian Splatting

Scene-wide settings for Gaussian splat rendering. Per-entity LOD range and falloff live on the GSplat Component.

Setting	Description
Radial Sorting	Sort splats by radial camera distance instead of view depth.
LOD Update Distance	Camera travel distance that triggers a Gaussian splat LOD update.
LOD Update Angle	Camera rotation in degrees that triggers an LOD update. Set to 0 to disable angle updates.
LOD Behind Penalty	Distance multiplier used for splat nodes behind the camera during LOD selection.
LOD Underfill Limit	Number of lower-detail LOD levels that can be used while optimal data loads.
Splat Budget	Target number of splats rendered across the scene. Non-positive values use the engine default.
Alpha Clip	Alpha threshold for Gaussian splat shadow, picking and prepass rendering.
Forward Alpha Clip	Alpha threshold below which splats are removed from the forward pass.
Min Pixel Size	Minimum screen-space size below which splats are discarded.
Min Contribution	Minimum visual contribution below which splats are culled. Set to 0 to disable it.
Foveation Strength	Strength of contribution culling towards the screen edges. Set to 0 to disable it. Only applies to the GPU-sorted raster renderer; on other renderers it has no effect.
Foveation Center	Protected screen-centre radius where foveation does not apply.
Anti-Alias	Apply anti-aliasing compensation to splats trained with anti-aliasing.
Use Fog	Apply scene fog to Gaussian splats.
Use Tonemapping	Apply camera tonemapping and scene exposure to Gaussian splats. Other scene objects are unaffected.
Color Update Angle	Viewing-angle change that triggers a spherical-harmonics color update.
Cooldown Ticks	Ticks an unused streamed splat resource waits before unloading.
Data Format	Work-buffer format used for Gaussian splat rendering. Options: Compact, Large.
Enable IDs	Store a unique component ID in the Gaussian splat work buffer.
LOD Mode	Metric used to select Gaussian splat detail within the global budget. Options: Error, Distance.

Exposure & Fog

Setting	Description
Exposure	The exposure value tweaks the overall brightness of the scene.
Fog	Controls an approximation of ambient fog in your scene. Types: None: Fog disabled Linear: Fades in linearly between Fog Start and Fog End distances Exp: Fades in from the view position according to an exponential function Exp2: Fades in from the view position according to an exponential squared function
Fog Density	Controls the rate at which fog fades in for Exp and Exp2 fog types. Larger values cause fog to fade in more quickly. Must be positive.
Fog Start / End	Distances, in scene units, where fog starts to fade in (start) and where it reaches maximum (end).

Resolution

Setting	Description
Resolution Width / Height	The width/height of your application in pixels.
Resolution Mode	Decides whether the canvas resolution changes when it is resized.
Fill Mode	Decides how the canvas fills the browser window.

Device & API

Setting	Description
Device Order	The order in which attempts are made to create the graphics devices.
Enable WebGPU	When enabled, the application will try to use WebGPU if available.
Enable WebGL 2.0	When enabled, the application will try to use WebGL 2.0 if available.

Rendering Options

Setting	Description
Power Preference	Provides a hint to WebGL regarding the preferred power mode: Default: Browser decides High Performance: Prioritize rendering performance Low Power: Prioritize power saving
Anti-Alias	When disabled, anti-aliasing is disabled for the back buffer.
Device Pixel Ratio	Multiplies the canvas back buffer resolution by the device pixel ratio (e.g., 2x on Retina). Increases sharpness and GPU/memory usage.
Transparent Canvas	Makes the canvas background transparent so the web page shows through. Useful for overlaying the app on custom page designs or UI.
Preserve Drawing Buffer	Preserves the drawing buffer until explicitly cleared. Useful for taking screenshots.

External Libraries

Setting	Description
Basis Library	Add the necessary libraries to support Basis compression.
Draco Library	Add the necessary libraries to support Draco compression.
