I have a cal3d rigid model and i try to set new rotation values on it's bones.

When I set the rotation values directly on CoreBone, the rotation correctly done (I can see the change).

When instead I set the new rotation values on CalBone, no change is done.

This is my piese of code
[code]

skeleton = calModel->getSkeleton();
bone = skeleton->getBone(boneID)
bone->setRotation(prevQuat * newQuat);
bone->calculateState();
//skeleton->calculateState();

[/code]

I am not sure that I posted the question in the right place, I still hope to get a hint from you.

Thank you in advance,
D.M.
