I've somes problems with bones, so I'll begin again all animation. So, I think I'll have less problems with shoulders.
I'll give you all skins "When it's done"

for the animation (I've again somes little things to change like whiter skin and true color for pants).
I've tryed to give a texture for specific animation and it work, so we'll be able to use painskins during the death of all evil ninjas.
The model has 2292 triangle polygones and textures has 1024x1024 pixels (

arg), but the game run always between 100 and 150 fps on my PC (ATI radeon 9600 pro (256Mo), Athlon 2100+ (1733Mhz)).
I've found a plugin to export md3, but I don't know how to configure it because it doesn't work exactly like md2 (in a md2, we've a name for each frame).
