np, glad to help (or to try ),

I would suggest sending one of your stripped down levels but with still the problem to gs3d support. They are helpfull and should indentify the problem fairly soon I think. Maybe also make a thread about it in the ask the developers sub section of the forum.

I think its either a bug or maybe some weird kind of feature of WED/static lights that we are overlooking.

Oh and you might also want to check in MED if the models dont have a custom material setting or custom shader set.
