When I update a FBX link in 3ds Max that i exported from Revit I end up getting a bunch of MultiMat_XX layers. I've isolated a few of the MultiMats and they seem to only have one material applied to them. When I orginally linked the fbx file there wasn't a problem. All of the layers were named after the material associated with them. The multimats only appeared after a few updates of the link. Also when I linked the file I choose to seperate by Revit Material. Is there a way to make it so that we don't have the MultiMats? What is causing the MultiMat?
