Hey PaQ,

is it possible that you send us the OBJ file causing problems? We will use it internally only of course. It is also okay to send only parts of the models if the issues are reproducable.

Why can't you test the NURBS in demo mode? Is your evaluation (30 day trial) running? we had expirienced issues where they trial won't activate correctly. If you are running in "free mode" (displayed in the welcome window) then please send us your Installation-ID (to be found in the License Manager) and I can send you an unlock code which will give you the 30 day trial.

Best,

Oliver
