ShadowBranch
This node generates shadows from a pass (such as a beauty pass) as well as:
1. Pruning all light materials and optionally all surface materials from the scene, even if the materials have already
been resolved.
2. Providing quick access to some PRman options that you generally want to have set in a shadow render.
NOTE: More information on details of settings picked up in the parameters can be found in the
PrmanGlobalSettings documentation.
