Looks like a nice package. The one drawback I see that needs to be addressed is that the package contains 1400 materials which implies that the user needs to mix and match the materials by loading/unloading materials. A very unweildly approach which could be solved by using a python script to create/edit materials on the fly. Also, if the angle of incidence node is used to create the cel outlines, then the package could only be used on Vue5I.
