You need the version for the game you're porting to, so in this case K1. Everything else seems fine, so if that's still not working, it's possible MDLEdit requires you to convert to ASCII, then load the ASCII before compiling. I usually do manual adjustments with KOTORMax rather than a straight port so I don't remember the specifics on that. And if that is the case, then you would likely have to do manual adjustments as well, because MDLEdit & MDLOps don't always get the smoothing groups right when converting.
