Hello, I'm brand new at VR model viewing. Really stoked at seeing my creations in real time. So I imported a car model into eyecadvr and some of the body surfaces were missing. I exported a Rhino 7.0 model with the eyecadvr plug in and I also opened an .OBJ file saved from rhino 7.0. Both had the same results.....missing surfaces. Please help! How do I see the whole model with all it's surfaces?
