bind_texture() [2/2]

void MayaFlux::Buffers::RenderProcessor::bind_texture	(	uint32_t	binding,
		const std::shared_ptr< Core::VKImage > &	texture,
		vk::Sampler	sampler = nullptr
	)

Bind a texture to a descriptor binding point.

Parameters

binding	Binding index (matches shader layout(binding = N))
texture	VKImage texture to bind
sampler	Optional sampler (uses default linear if null)
