Do the textures look dithered? Do you have 1 meg TRAMs or 4 meg TRAMs on this
IMPACT? You will see dithering with 1 meg TRAMs.

This is a zbuffer resolution problem you have to move the objects further
apart, use the pfLayer facility ,not sure how this is done in MultiGen, or
shorten the distance between the near and far clipping plane. You have already
done the thrid solution this increases the resolution of the zbuffer allowing
your objects to be properly sorted. Probably the most universal solution would
be to implement pfLayers through MultiGen.
