Vornado...I got that error a couple days ago on a save. Through the process of elimination I traced it to a specific TIF with an alpha channel I was using as a texture. I couldn't find anything about that TIF that was different from others I was using (that also had an alpha channel, used the same compression method and were saved out of the same program). I did send it to Corel (I'm a beta tester) so they can figure it out. I've done literally dozens and dozens of scenes with Bryce 5 and only ran into it that one time. Spit
