I have had this problem before but never found an answer to it. I rendered the model in Vray, and there were strange shadows everywhere (I think I accidentally put a bunch of lights in the model because I don’t know what I’m doing). When I test rendered it, the model came out entirely yellow. This is my first time this has happened with vray but the same thing happened when I render in Visualizer. What is messing the model up? Last time Visualizer rendered a yellow model but this time it is blue. It must be a sketchup problem if it’s throwing both off. Please help, I am desperate to finish this model!
