I've been inspired by Barrel of Monkey's Saga armor. We need some long barbarian hair to go with it. Come to think of it, it would be nice have some Native American style braids (laying in FRONT of the torso), and some shoulder length dredlocks.
Well these ideas could go on forever. We just need more hair.
Whatbrick's NWN2 Character Customization Collection has such a hair, but for women. Maybe it could be transported for men. Maybe it is a good idea to ask the author about it!
But it has a bug: when the long-haired character is running, his hair behaves like a curtain. It goes up and down in unnatural way. One can install the mod and see it by his own eyes. So, it is necessarily to check this bug, I suppose.
