No, not at all.

There's always a tricky way, just not always an easy one. ;)

I could see two things: are the models loaded from VRML? The VRML loader
ignores the Geometry's material, and uses a MaterialGroup on top of the
Geometry for setting the Material. So go to the parent and change that
Material for VRML.

If not, remember that the SimpleTexturedMaterial does add its own
TextureChunk to the system, so if you add one, it will be the second one
and will show up in the second texture unit.

If that's not it either I would need some more info on what exactly is
going wrong.
