Hello, You can do this, however, this is deep in the Cal3D data structures. osgCal is only a thin rendering wrapper. This is going to be from hazy memory from about 6 years ago when I did this, so do not take me for my word here. What you have to do is to get a pointer to the Cal3D Model instance (I think it was that - I believe osgCal allows you to get the pointer), from that you can get to the individual bones. However, if you try to drive the bones manually, you need to disable the default animation mixer or your data will be overriden. The way to do that is to manually call the individual functions to update the skeleton, to update the skin, etc, but do not update the animation mixer. You will need to make you own mixing if you want to e.g. move the head on top of another animation. Overall, it is doable, but it is quite a mess - Cal3D is not designed with procedural animation in mind.
