Detailed Description

Dynamic primitive/instance data for a mesh batch element.

NOTES:

• When applied to a FMeshBatchElement, data provided to the TConstArrayView members are expected to live until the end of the frame on the render thread
• If DataWriterGPU is bound and the TConstArrayView members are left empty, the delegate is expected to write any missing data, as it will not be uploaded

EnableInstanceDynamicData()

void FMeshBatchDynamicPrimitiveData::EnableInstanceDynamicData ( bool  bEnable )

inline

EnableInstanceLocalBounds()

void FMeshBatchDynamicPrimitiveData::EnableInstanceLocalBounds ( bool  bEnable )

inline

EnableInstanceSkinningData()

void FMeshBatchDynamicPrimitiveData::EnableInstanceSkinningData ( bool  bEnable )

inline

GetPayloadFloat4Stride()

uint32 FMeshBatchDynamicPrimitiveData::GetPayloadFloat4Stride ( ) const

inline

Computes the full float4 stride of the instance's payload data. NOTE: Needs to align with GetInstancePayloadDataOffsets in SceneData.ush

inline

SetPayloadDataFlags()

void FMeshBatchDynamicPrimitiveData::SetPayloadDataFlags ( uint16  Flags, bool  bValue  )

inline

Validate()

void FMeshBatchDynamicPrimitiveData::Validate ( uint32  NumInstances ) const
