Description

Similar to RHIDrawIndexedPrimitiveIndirect, but allows many draw arguments to be provided at once. GRHIGlobals.SupportsDrawIndirect must be checked to detect support on the current machine. @ param IndexBuffer Buffer containing primitive indices @ param ArgumentsBuffer Buffer containing FRHIDrawIndexedIndirectParameters structures @ param ArgumentOffset Offset in bytes of the first element in ArgumentsBuffer that will be used for drawing @ param CountBuffer Buffer containing uint32 count of valid draw arguments that should be consumed (may be nullptr, indicating that only MaxDrawArguments value should be used) @ param CountBuffeOffset Offset in bytes for the CountBuffer element that will be used to source the draw argument count @ param MaxDrawArguments How many draw arguments should be processed at most, i.e. NumDrawArguments = min(MaxDrawArguments, ValueFromCountBuffer)
