Im new around here, and I think I have started with quite a difficult model for my skills. I need a bit of help. The model is done with Rhinoceros 5, I tried to make every mesh closed (and by Rhino's standards they are) but I have some troubles with netfabb. Even if I try to heal the model, it keeps giving me the "alert" sign. Also, I have problems with the colors. I want to make it Full Color Sandstone and I dont really know how. Ive uploaded the .3dm model with all the colors and the .stl model as healed as I could get it with Netfabb. So, any help about this will be welcomed. The model turned out pretty cool, you can perfectly use it if you want it.
