Cool and yes, they can fall victim to moire. The best way to avoid it is to make sure your uv's are as uniform as possible so that all polys gain the same amount of texture info (which is nearly impossible to do) and break up the pattern with some dirt or wear and tear. Though if you're making a product it may be wise to include a non-damaged version so that folks can add their own if/as needed. Anyway, glad to see folks using it and having fun with it. That was the whole point of me sharing. :)
