I don't know if this is the problem,but it could be: I don't know what colordepth your .pct is, but if it's 32bit then that could cause the problem. Bryce renders at 24 bit and if you change 24-bit RGB to 32-bit CMYK the colors change a little. Photoshop has a color algorithm build in that changes what you see on screen. It's very handy when you convert 24-bit to 32-bit images, because the output always is exactly the same on screen. If bryce changes the colordepth, you get differences in the colors and brightness.
