Ugghh... well, I tried making Zack's hair longer and this is the result:

Not that I'm very proud of the result, but I don't think I can make it better without making the model SD.
I also changed the up-part of right arm and the down-part of the left one in order to test one new featue I'm trying to implement in my program (in order to re-use non-simetric limbs). Too bad I have no idea how to deal with the normals, because it looks like FF7 won't render the models correctly unless they have consistent normals

.
Oh about changing the battle model's hands Goku7, I think it's a good idea. The current version of my program it's not enough to do it yet, though. You would need to change the brightness level. I've implemented this already, but I didn't include it on the last release because it wasn't working right. I'll put it next time.
