Functions
void	SetbUseTwoSidedLighting (bool Value)
	If true, this object will be lit as if it receives light from both sides of its polygons.
void	SetbShadowIndirectOnly (bool Value)
	If true, this object will only shadow indirect lighting.
void	SetbUseEmissiveForStaticLighting (bool Value)
	If true, allow using the emissive for static lighting.
void	SetbUseVertexNormalForHemisphereGather (bool Value)
	Typically the triangle normal is used for hemisphere gathering which prevents incorrect self-shadowing from artist-tweaked vertex normals. However in the case of foliage whose vertex normal has been setup to match the underlying terrain, gathering in the direction of the vertex normal is desired.

Public Attributes
Lightmass
float32	DiffuseBoost
	Scales the diffuse contribution of all materials applied to this object.
float32	FullyOccludedSamplesFraction
	Fraction of samples taken that must be occluded in order to reach full occlusion.
float32	EmissiveBoost
	Scales the emissive contribution of all materials applied to this object.
