Hi Nick, You are correct on both accounts. If your Modeling App alows you to save using Layers & Materials you should get the layer names and the materials. (I have had trouble with screwed up polygons with this method). Don't know why. If you save using Objects & Materials you should get numbers for your layer names. By "Simple Materials" I mean regular colors like red yellow blue etc. You can name them things like Masonry 1, Stucco 1, Stucco 2, Glass, Shiny Metal... Whatever you want, and the names will be attached to the materials that you will modify using the Material Editor in Vue. It works quite well, and then the layers don't matter. Once you do this the first time, you can save the materials to your personal material pallet. That way if you have to modify the building or object, you can quickly delete the old one, and import the revised object and reassign the materials throught the editor again. You won't have to tweak the materials again because you saved them. Hope this helps. Tom
