Matt! Thanks so much for responding. I didn’t realize that there was a separate “update lights” button. I was thinking that simply clicking “update” would take care of it. When I did do it, I got a very odd result. After several attempts and adjustments, I punted on the entire layer in AE and deleted it. I had saved the scene in 3DIP and knew it would be easy to do over. Sure enough, when I applied 3DIP to a new layer and opened the saved scene, everything worked as advertised. Thanks for helping me solve this.
