I've been trying to to the tagliatelle of the gods tutorial and some of the renders have been ok and some have not. The ps files are not compressed and the pixelation effect can be seen on screen in Bryce which kind of leads me to the depth of field theory. My camera may be too close to the cube. The only other thing I come up with is perhaps the original photoshop images may need to be square rather than rectangular to better fit the cube dimension. Mivan
