Why when I turn the skeleton in animation mode at 360 degrees it does not work?

One more question.
How to export original esenthel skeleton into any 3D Model Editor (Milkshape, 3DMax, etc).

Howmany frames did you use to make him turn? I'm just guessing here, but isn't it just interpolating between the frames, taking the shortest 'route'? In this case, if you don't have any frames between him standing vertical and back normal, he would rotate back. Try adding more frames?

I believe Tottel is right regarding this, seems to be the problem. : )

Doesn't work. New video shows it.

With orientation keyframes same problem.

Hi, the rotation keys don't support this function, but orientation do support it, I've just tried it.

It really worked Sorry.
