>> I have been rendering at .7 to 1.0. Anything above this starts to show >> stripes in solid colors. Is this due to my using 640×480 res? 3ds does not have gamma settings below 1.0, so I assume you are using TCONFIG to set a gamma correction. This in effect takes a 24 bit image and gamma corrects it, which may result in banding. Also, I believe 640×480 has a 16-bit color depth, which dramatically increases banding. Your best bet is to -NOT- use Tconfig, but rather set up your Targa board with "TMODE 11 6" which will give you NTSC interlaced 512 x 486 output. This you can run to a video monitor or even a TV's video-in jack. If you must go to a VGA monitor, try "TMODE 35" (512 x 400 NI) or "TMODE 36" (512 x 496 NI). – THEN – Set your gamma control via 3ds. 3DS corrects down from 48-bit color depth to the final 24 bits, for rich colors with no banding. There is a file in the libraries called R3GAMA.ZIP (I think), that contains discussions about gamma correction. – Dave
