update_chain_render_range()

void MayaFlux::Buffers::NetworkGeometryBuffer::update_chain_render_range	(	size_t	index,
		uint32_t	vertex_offset,
		uint32_t	vertex_count,
		const std::optional< Kakshya::VertexLayout > &	layout
	)

Update vertex range for a specific operator chain index.

Parameters

index	Operator chain index
vertex_offset	Starting vertex offset for this chain
vertex_count	Number of vertices for this chain
layout	Optional vertex layout for this chain (if different from primary)

This allows the processor to push per-chain vertex ranges to the RenderProcessor, enabling it to issue draw calls for specific subsets of the geometry.
