so I've installed the software and drawn a wall and a couple of windows, straight from the default tool palette. I then check the new RPREF palette to make sure materials will be applied during rendering. I check the materials are applied in the style and they are. I change to the 'realistic' shade mode and it all looks OK. I then go to render and no materials are applied, even the glass, which doesn't use a texture map.
Is there a setting autodesk have added to cause this?
