Values

Name	Description
PrimID_FromPrimitiveSceneInfo	PrimitiveId will be taken from the FPrimitiveSceneInfo corresponding to the FMeshBatch.
PrimID_DynamicPrimitiveShaderData	The renderer will upload Primitive data from the FMeshBatchElement's PrimitiveUniformBufferResource to the end of the GPUScene PrimitiveBuffer, and assign the offset to DynamicPrimitiveShaderDataIndex.
PrimID_ForceZero	PrimitiveId will always be 0.
PrimID_Num
PrimID_NumBits
