Jay from SimplyMaya.com takes a look at the Use Background Shader in Maya, which will allow you to control some surfaces of you Maya scene for compositing, such as catching reflections, specularity, and shadows without actually rendering the object itself.
“This week Jay explains how you can incorporate a 3d model onto a 2d background with Maya’s use background shader. The method shown here will allow you to cast shadows onto an image and make the model sit more realistically in a composite. We take look at alpha channels, isolating shadows in a render and how the appearance of shadows can be controlled within Maya using the shader node itself, as well as how to gain a higher level of control in post applications.”
