The Look File Manager
The LookFileManager is provided to simplify the process of resolving Look Files, applying global settings, and allow the users to specify overrides such as for materials. This is a SuperTool that makes use of many of the more atomic operation nodes mentioned previously such as LookFileResolve, LookFileOverrideEnable and LookFileGlobalsAssign.
In particular it is designed to help make setting material overrides that need to be applied to some passes but not all passes a lot easier for the user.
