How do I prevent Viz from reverting the scene material "Global" to an architectural type material when I import a dwg? I use vray as my shader, and typically setup "Global" to be the most widely used material in the scene which is usually a concrete type material. When I import a new dwg, however, global gets overwritten by a default architectural type global without warning and without asking.
Architectural type materials are not compatible with vray and so I have to constantly re-import my saved Global mat to overwrite the one that viz automatically creates for me every time I bring in new geometry. Vray compatibility aside, this is an annoying bug that seems to have no purpose and no clear way to disable. It's not an option in the dwg import dialog.
Any help is greatly appreciated.
