Now for some reasons I'm setting forces/torques manualy. With forces
it works idealy all translations given from animation works, but when
I try with rotations then comes troubles: everything works to fast and
output rotation looks strange.

I'm calculating torques like this:

old_angle = get_euler_angles (old_transform);
new_angle = get_euler_angles (new_trandform);
new_ang_vel = (new_angle - old_angle) / delta_time;

old_ang_vel = body->get_angle_vel ();

torque = Inertia * (new_ang_vel - old_ang_vel) / delta_time;

any help?
