Variables
| Type | Name | Description | |
|---|---|---|---|
 |
FExpressionInput | Albedo | The single scattering Albedo defining the overall color of the Material (type = float3, unit = unitless, default = 0) |
 |
FExpressionInput | AmbientOcclusion | Ambient occlusion: 1 means no occlusion while 0 means fully occluded. |
 |
FExpressionInput | EmissiveColor | Emissive color of the medium (type = float3, unit = luminance, default = 0) |
 |
FExpressionInput | Extinction | The rate at which light is absorbed or scattered by the medium. |
