Here is a wire of what I’m working on:
I want to add oil to this illustration. It will be clean oil so it will be quite transparent. It will need to conform tightly to the gears in various places.
How would you go about getting the oil to conform to the gears? The selected section in the wire above is the approach I was going to take. I was going to extract the region and then tweak and extrude from there. The problem is that if I extract that region it creates a backface with no geometery. Is this a problem? Here is a shot of what I mean:
This goofy geometry may create issues when exporting to OBJ and re-importing into Carrara for texturing and rendering. Is there a way around this?
Here is one thought. I could extract each face individually. Then group them and extrude from there. Would that create proper backside geometry?
All in all, is there a better way to approach this entire thing?
