Hum.. No... I don't have any 3D model... I think I will try to make one frame by frame using .BMPs extracted from Sprite Creator. It is a long process but is is handy. You just export the frames you need and they come already with a alpha channel. You just have to modify the sprite a little in Photoshop, modify the Alpha channel if needed and voilà. I'll give you back some news of it when I'm finish.
