can anyone give more details about turning off and on textures.
The problem, as far as i can fathom is that perfromer seems to only
handle 2 states:
        nothing is textured
        everything MUST be textured.

The problem is that I want to create a database where only some of the
objects are textured, but what happens is that those obects that don't have a
texture pick up whatever was the last texture definition.

[ i have tested this with the default perfly by viewing 2 identical
wavefront models; one with a texture and one without, and they both pick
up the texture ]

I looked at pfOverride but in order to apply a texture you have to set
pfOverride(PFSTATE_TEXTURE,0) and then the texture will be applied to ALL
geometry, and if i set pfOverride(PFSTATE_TEXTURE,1) i can't apply ANY
textures!

has anyone had any success in this area ??
