I’ve been using the VR hands animations/poses and they’ve been working great so far. However now I’m in need of another pose that’s basically the hand pointing with an index finger. How would I go about doing this?

I’m looking to make it basically add on as another animation state like these poses:

Any help is appreciated as I’m very inexperienced when it comes to the 3d modelling stuff!
