The lighting model to use for lighting a
ModelExperimental.Properties:
| Name | Type | Description |
|---|---|---|
UNLIT |
Number | Use unlit shading, i.e. skip lighting calculations. The model's
diffuse color (assumed to be linear RGB, not sRGB) is used directly
when computing gl_FragColor. The alpha mode is still
applied. |
PBR |
Number | Use physically-based rendering lighting calculations. This includes both PBR metallic roughness and PBR specular glossiness. Image-based lighting is also applied when possible. |
Experimental
This feature is using part of the 3D Tiles spec that is not final and is subject to change without Cesium's standard deprecation policy.
