set_buffer_vertex_layout()

void MayaFlux::Buffers::RenderProcessor::set_buffer_vertex_layout	(	const std::shared_ptr< VKBuffer > &	buffer,
		const Kakshya::VertexLayout &	layout
	)

Override the vertex layout used when building the pipeline for buffer.

Parameters

buffer	Target buffer (key into m_buffer_info)
layout	Layout specific to this processor's topology

Called by CompositeGeometryBuffer to give each RenderProcessor its own topology-specific layout rather than the shared aggregate on the VKBuffer. Triggers a pipeline rebuild on the next execute_shader() call.
