I had a strange problem when displaying a model (MultiGen .flt file)
on an Onyx with Reality Engine 2 graphics, using Perfjoy or Perfly.
On the texture mapped walls there're visible color bands, but the
texture map is greyscale (though I can't say the rgb values are
the same for any pixel). For some faces the mapping is largely
correct but with color bands, for others the color is not correct
at all.
I'm using very small textures (e.g. 16x16). I tried to display
the same model with the same software on an Indy (with no hardware
texture support) and the result is correct. I mapped the texuture
to a square using OpenGL and it works O.K. So the problem should
be somewhere between Perfly and the graphics hardware.
Any suggestion will be appeciated!
