I just fiddled with the attic file. Loading it into P4 PP, I got 21 lights and shadowcams, and I was able to delete all of them. Then I added a spot, which came in as Light 1 with Shadow Cam Lite 4 attached. I'm trying the file in P5 now. I just did the same thing in P5, and got the same result. And my shadowcams to not have underscores in their names. I'd be very curious to see the file you are having trouble with. Mick
