Variables
| Type | Name | Description | |
|---|---|---|---|
 |
uint32: 1 | bShadowIndirectOnly | If true, this object will only shadow indirect lighting. |
 |
uint32: 1 | bUseEmissiveForStaticLighting | If true, allow using the emissive for static lighting. |
 |
uint32: 1 | bUseTwoSidedLighting | If true, this object will be lit as if it receives light from both sides of its polygons. |
 |
uint32: 1 | bUseVertexNormalForHemisphereGather | Typically the triangle normal is used for hemisphere gathering which prevents incorrect self-shadowing from artist-tweaked vertex normals. |
 |
float | DiffuseBoost | Scales the diffuse contribution of all materials applied to this object. |
 |
float | EmissiveBoost | Scales the emissive contribution of all materials applied to this object. |
 |
float | EmissiveLightExplicitInfluenceRadius | Direct lighting influence radius. |
 |
float | EmissiveLightFalloffExponent | Direct lighting falloff exponent for mesh area lights created from emissive areas on this primitive. |
 |
float | FullyOccludedSamplesFraction | Fraction of samples taken that must be occluded in order to reach full occlusion. |
