Hi There!
I am facing a unique problem with my sketchup vray. And the rendering process n this particular model has gone staggeringly slow. And after a bit of searching for anything unusual, There appears to be some materials present in vray material editor which is not here in sketchup materials named, 'image1, image2, image3, image4'. Once I remove these materials by right clicking, they gets removed for a second and appears again. Hope somebody could help me.
