What problems may it cause to change bone lengths Alhexx?
If you change the bone lengths without changing the animation files, then you have a good chance of screwing up your animation.
If you only change the bone lengths a bit (maybe < 10%), then it should be no problem. However, if you change the bone length ~90%, then the animation will (or can) look simply strange.
If you never had any problems with it, then you had luck.
If I recall correctly, FF7 does not have smoothing groups.
Although I'm not 100% sure, I think that you are right.
The battle models are shaded using vertex coloring (you can call this "static per-vertex-lighting" if you want), and for that reason, the battle models do not have any normal vectors.
I'm not sure about the field models, since they do have normal vectors, and IIRC, these are used on the world map...
