I see! It does leave some challenges to making it seamless yet, though. I suppose I'll have to generate some new and bigger texture files if I want one part at a time. Thanks for the tip though!
Still there's one strange issue. There's not a very catastrophic seam between the hips and torso, but it looks actually detached in-game, as if a shadow comes between at certain angles (in certain lightings). I don't think it has to do with the texture. In modview, it doesn't behave that way obviously since there's no lighting, so that might prove that it has to do with the lighting in-game. Any idea what causes this?
