Variables

	Name	Description
uint32	BytesPerElement	Stride in bytes for index and structured buffers.
uint32	NumElements	Number of elements.
EUnderlyingType	UnderlyingType	The underlying RHI type to use. A bit of a work around because RHI still have 3 different objects.
EBufferUsageFla...	Usage	Bitfields describing the uses of that buffer.
