Render layers and passes

This was the shot given to me for this particular assignment

And this is my attempt at recreating this in maya below-

I have used both render layers and render passes to render the above  scene and then compiled them in photoshop

Render Layers

Render layers help in rendering a large scene or scenes with multiple lit objects.Each object can be separated and grouped into different layers and rendered to their particular render requirements

Render passes

Render passes render the  different attributes of a scene separately,such as Beauty pass,shadow pass,specular pass
