RE: Color keying Adam Hoult (2 replies, 0 views) (2000-Jul-5) Well Color Keying is almost a dead feature in Direct3d for textures, and some newer cards don't even support Color Keys for texture surfaces (DOH !!!). The way that is presented to us, is to use ALPHATESTING to remove irrelivent coloured pixels.
Anyway, if you have Dithering or Bilinear Filtering turned on, this will cause the problem (since texels are averaged before being displayed when using filtering), if you turn filtering off, this problem does not occur.
