NOTE: A common misconception is that the Maya "Ray Depth Limit" on the ray traced shadows is how many surfaces the shadow rays penetrate. But as the title says. AMD Radeon™ ProRender is AMD's powerful physically-based rendering engine that lets creative professionals use open industry standards to leverage GPU and CPU performance to produce stunningly photorealistic images in Autodesk® Maya®.

We will also use the shadow_matte shader to composite the car model onto a photographic backplate. Now Render the Maya scene: Render-> Render Current Frame You should get an image like the one below. 1.) This can save even more time. It is, in essence, a "trick" that can help emulate multiple scattering, i.e. Arnold is, since 2017, Maya's default render engine.

One Maya render took over an hour! The plugin also connects Maya with RenderMan Pro Server, through its RIB-out functionality and advanced integration with the renderer.
