Animating Mixamo Rig

Hi. I am new to animation, rigging, etc.

I downloaded a walking cycle from Mixamo. Imported into Blender (FBX) and just cycle the animation in order to have my guy continuously walking in the same place. After that I added a constraint “follow path” and made the guy walk on the line. So far everything is walking.

I would like to use this character into a small animation I am doing. The guy needs to have a toolbox in his hand (which I already modeled). I am trying to make his left hand to shape into a claw position.

I jumped into Pose Mode and rotate the little spheres (hand bones) and the hand got exactly as I wanted, but now when I play it the guy just returns to its position.

Again I am totally new with animations and rigging. I would like to share my scene, but I was thinking that Mixamo works with the adobe membership, so probably my rig its kind of limited to legal non shareable things on internet.

How can I help to provide more information?

Thanks

You’ll have to set a key frame (hotkey is “i”) for the hands new pose and propagate that thru the walk cycle animation.
