@mtmckinley Thank you very much for that hint! I just watched the movie and immediately downloaded the program you used called VideoMach, so I am going to render it frame-wise... I only fear that my memory will not be sufficent... It's very close every time with each single image, I have to restart Maya before every frame-render with all details to not get an error message "free memory is low"... Will it work anyway, maybe Maya will empty the memory after each and every rendered frame? Hop so Best Regards Markuz
