configure_back_buffers()

void MayaFlux::Buffers::BufferUploadProcessor::configure_back_buffers	(	const std::shared_ptr< Buffer > &	target,
		std::vector< std::shared_ptr< Buffer > >	sources
	)

Configure sources to upload into every entry in a VKBuffer's back_buffers, re-read every processing cycle.

Parameters

target	VKBuffer whose back_buffers is being written in full.
sources	CPU-side buffers to read from, one per back_buffers entry, in order.

back_buffers.size() is read fresh each call. If sources.size() does not match at process time, the call is skipped with an error rather than partially applied. Direct memcpy per entry; entries without a mapped_ptr are unsupported and logged as an error rather than silently skipped.
