Check out SGI's corporate headquarters in Performer -- it was done with
Wavefront and gives you an idea how sophisticated the interface is.
It's in the "friends" directory. On my machine its
/usr/src/Performer/friends/site, then launch sgisite.

The only issue is not using .txc, .txb, etc for textures -- you're
stuck using rgb images. If you have an alpha plane in the rgb
transparency does work -- look at the trees in sgisite.

If you look at the perfly source code, in libpfsgi/pfobj.c, it
shows what options in the obj file format are supported.

If you haven't figured this out already, you need to add a line at the
start of every obj file to reference a material file. You can do this
through the Wavefront interface with "properties->material file..."
then specify the material file that you use. Or do it by hand
by adding "mtllib <absolute path to material file>"
