Follwing this (
http://www.lucasforums.com/showthread.php?t=193050) tutorial, I used MDLOps before modeling the head to give it the ascii extension. Then, I modeled the head with that extension. After it was modeled I used tainas replacer.
EDIT: I have read everywhere that failing the sanity check doesn't make a difference, but mine is excessively long; it's probably over 500 lines, all saying vertices in <insert sub-part here> (ex: head_g) need to be welded. And ending in "weld check failed". Could this be a problem or does it always happen and not have any effect?
Edit: Sorry for this bump, but I'm fed up. Every time I model a head in either game this happens to me. Does *anyone* know what causes my problem? This can't be that uncommon. What am I doing wrong?
Edit: And now the little box around the head disappeared so I can't export it and try again. How can I get that back? I must be making this harder than it has to be.
