Ed, Stupid Answer: The only thing that I've found that causes that is mapping infinite planes. I've also seen it happen with centerpoints that are far away from the actual midpoint of the model. I find this occurs when I build a whole model in vertex mode then try to split it up. I tend to do a LOT of vertex modelling and I see this frequently. When it happens I have two choices. Live with it, or save and reload. Not the answer you wanted to hear, I think, but an answer of sorts.... Ken src="http://market.renderosity.com/~carrara/emoticons/dork.gif">.zip
