I picked up a free model from the internet and now for the life of me I can't get it to render. I tried several basic materials.... lambert, blinn, etc. I check the object's visibility and possible hidden attributes. I even duplicated the object deleted its history and it still will not render.
There is however an anomaly that shows up on the right click pop-up menu. There's a selection for painting skin weights. Not sure what that's about. This mystery model has gotten me baffled.
