Note that if you purge in Sketchup, those materials won’t be assigned anymore and it will render a black model. The only workaround I have found is to paint a grouped face and bring it along with the proxy, so the materials remain in the model.
Hi Eqc
Sorry for late reply and thank you very much for your explanation. I will try to place the material again or try do delete the material in VRAY and import the proxys again. Maybe that will work.
At least I have a way to go and an explanation! Thanks!
