I think the geometry-exporter should get the materialname to use as a parameter.

There are some other problems to resolve regarding to materials. I think the best idea will be to have a seperate (user-defined) node in a Poser material with hints for Lux-Materials - and a name to use.

Because we need a wacro for this, this wacro is able to make sure we have unique names for a scene.

Another advantage is that we can create special Lux materials, point to this materials from within Poser and adjust parameters via Posers Materialroom.

The scene-collector part of the exporter can check if Lux materials are defined and, if not, can try to make a best guess. So the geometry-part can be sure to get unique materialnames (and if a materialname is not unique, this is what the user wants).

What do you think?
