Sorry to hear about your render problems.... I to have had problems with rendering in the assemble room. Funny thing, carrera gave me a couple "unknown error has occurred" messages while working on this piece and I had to restart the program. However, my system did not crash. For this experiment, I actually turned off all settings (lights, bump, etc) to do test renders of the full animation until it looked right. This mainly was to improve the render speed. The finished product was rendered with all options turned on in the renderer and saved as an animated gif. It was a quick test so I did not try to make everything look "perfect". (Note: The car model came with Carrera.) .Painter
