I just remembered... There is an export option you might try:
lighting=<value> Specifies a default enable/disable state for lighting.
By default, the exporter assumes lighting is enabled (GL_LIGHTING ON).
Set this to either ON or OFF. Example: "lighting=OFF".
It's been a while since I looked at the code, but if you pass
"lighting=OFF" in the Options string, then the exporter might handle
materials differently. I'm not sure about this; check the code to see
exactly what the effects of this option are.

Hi Paul,
thanks for the fast answer and clarifications regarding handling of materials in osg, OpenGL and OpenFlight. Seems like I have not considered the whole picture. I made a few tests and everything looks fine indeed. So I aggree, this behaviour should be the default.
For various reasons these 'added' materials are problematic for some of our applications, but I think I will find a workaround or will - as you suggested - implement and submit an alternative way for the Plugin. Have to rethink about this.
Thank you!
Cheers,
Katharina
