Renderman look development tutorial | Renderman 22 pxrLayer Surface

Welcome to using the pxrLayer surface shader in Renderman 22 for Maya tutorial.
Layer shading is a common technique in CGI. In this look at the layer system found in Renderman 22, we will examine the global versus the layer-specific settings. The layer system builds on the previous lesson pxrSurface shading. In visual effects, layered shading is commonly used to add detail or blend between material properties. I will use a Cinema style lens to combine a few Material layers using a mask gizmo generated in Mari and a scratch aluminum bump generated in Substance Designer.
