1) Not sure if its an Autodesk thing, or a Itoosoft thing. In general, the tick for Consolidate Materials is not being recorded by State Sets.
2) Also, if the Geometry is based on the Laubwerk library, on creation, the option for "Merge into scene/XRef to library" is greyd out, and the consolidate Materials tick have no affect either way. In these cases, I'm not sure where the material is coming from as the material slot is empty. If I change the material I can not get the original material back wihtout reloading the object from the library
