Hand grab animation with Vive triggers

So basically I’m trying to figure out how to animate the players hand models when you press the trigger on a vive controller. Depending on how far down the trigger is pressed, the more “clenched” the hand will be. I figured the best approach would be to get the axis value of the trigger input by setting it to a float, and setting a float parameter in the animator for the hand animation, however I can’t seem to get this working. Both hand models are also rigged.

Well your idea is correct and should work depending how you setup it. Simplest way is to have a blend tree with 2 poses, open and closed hand frame and then blending between the two based on your param. Depending of your hand mesh you can make it look better and more natural by using more poses to transition between.

Used a blend tree, with two different hand poses and it works perfectly now. Thanks very much for the help :slight_smile:
