struct FRayTracingGeometryInstance

Variables

	Name	Description
bool	bDoubleSided	Disabling this will allow ray hits to be registered for front and back faces.
bool	bForceOpaque	No any-hit shaders will be invoked for this geometry instance (only closest hit)
FRHIRayTracingG...	GeometryRHI
FShaderResource...	GPUTransformsSRV	Buffer that stores GPU transforms.
uint8	Mask	Mask that will be tested against one provided to TraceRay() in shader code.
uint32	NumTransforms	Transforms count. When GPU transforms are used it is a conservative count.
TArray< FMatrix...	Transforms	A physical FRayTracingGeometryInstance may be duplicated many times in the scene with different transforms and user data.
TArray< uint32,...	UserData	Each geometry copy can receive a user-provided integer, which can be used to retrieve extra shader parameters or customize appearance.
