SPV_EXT_shader_viewport_index_layer enables using ViewportIndex and Layer in vertex and tessellation shaders. Also, as per the Vulkan spec: > The ViewportIndex decoration must be used only within vertex, > tessellation evaluation, geometry, and fragment shaders. > In a vertex, tessellation evaluation, or geometry shader, any > variable decorated with ViewportIndex must be declared using > the Output storage class. > In a fragment shader, any variable decorated with ViewportIndex > must be declared using the Input storage class. Similarly for Layer.
