Another question, guys...Look at the image I used as the thumbnail for this thread. You can see there is odd-looking geometry all over the place. That's not actually there; what you are seeing is behind the surface. If I zoom in a bit, it disappears. The pieces aren't intersecting anywhere, and it renders just fine, so why are parts of the model see-through in the viewport?
Oh! Related question! Isn't there a way to render a model and have all the edges visible? I'm sure I've seen such an option somewhere.
