I know that you can do this with code, I *have* done it before, a long time ago and it was with WDL anyhow. I need to know how to combine vertex and bone animation for a specific purpose.

My model is animated using vertex animation, I want to add one bone for the character's head and rotate that bone to face the mouse to allow the character to look at the mouse pointer. The problem is that when I do this, the character will not animate using the vertex animations, even though there are no actual bones animations in the model.

I just need to know how to animate it using vertex animations while being able to modify the bone rotation at the same time. Everything else works great, that's the only thing that I need help with.
