void MayaFlux::Portal::Graphics::ShaderFoundry::update_descriptor_buffer	(	DescriptorSetID	descriptor_set_id,
		uint32_t	binding,
		vk::DescriptorType	type,
		vk::Buffer	buffer,
		size_t	offset,
		size_t	size
	)

Update descriptor set with buffer binding.

Parameters

descriptor_set_id	ID of descriptor set to update
binding	Binding index within the descriptor set
type	Descriptor type (e.g., eStorageBuffer, eUniformBuffer)
buffer	Vulkan buffer to bind
offset	Offset within the buffer
size	Size of the buffer region
