VR - attaching a 3D hand to a 3D controller and using Unity's XRInputToolkit to move fingers & thumb
Buy the hand on assetstore: https://assetstore.unity.com/packages...
And source code for the Update loop (this assumes you've setup a link to your AnimationController already).
PS: I might do these "properly" and re-animate the hands myself so they fit perfectly. If so I'll post something on the asset store (and will do a bunch of different assets so you can import any of them). But it takes a while so ...
NB: YouTube blocks the video if there are "angle brackets" anywhere, which is pathetic. So you'll have to re-instate the ones I was required to delete. Sigh.
PPS: apologies for poor mic - the foam got torn off and I haven't replaced it yet.
