I have problems understanding how to manipulate the
material of an object. I read in a scene description
file, which is ordered by Light sources, Materials
and Objects. Each Object has a material tag and when
I read an object (from an external file with LoadObj)
and want to assign it the appropriate material.
The pfMaterial man-page only explains how to apply
a certain material to a GeoSet, which then could be attached
to a Geode. But LoadObj doesn't return a Geode
(I got the message: Performer Warning (9): pfAddGSet() geode is not a
pfGeode). If I would use pfApplyMtl, that would apply
this material to all the geometry in the database.

So I am clueless, how to
a) specify a material for a specific object read via LoadObj
b) change the material once specified for such an object.

Any help would be appreciated,

Torsten Moeller
