Syntax

struct FMeshBatchDynamicPrimitiveData

Remarks

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
