Hey Radiance, I see what you're saying, but the problem is the materials didn't carry over correctly. I imported a car and the body and windshield have the same material assigned to them, so I can't just swap materials.

yeah, I knew about that, but that's just for changing materials that are already assigned. I was wondering if there was a way to add a new material to a specific surface.

I see a bunch of triangles in the graph editor, which I assume are all the materials in my scene. I've added a specular node, but how do you add it to the correct surface? Thanks.
