I had read in an animation article long ago that it is important to add effort in humanizing the eyes and hand animation because thats where people look at.

Lets focus on the hands for now.

Importing a bvh humanized V4's movements but the hands and fingers stay stiff. Though I could apply hand poses, the results can be dissatisfying or the process time consuming.

Is there a way to naturalize the hands and fingers with subtle grasping like how a real person uses his hand gestures when in a coversation? 

You know what guys I got it. Darn, ideas doesnt go fast enough in my brain.

Thanks for reading anyway. 

SO......

what did you got, so the rest of us can get it?

Oh yes. Excuse my momentary selfishness.

I used a python script by Ockham: Jiggles

All you need to do is to select the hand, run Jiggles script, analyze then put all MTs to its lowest value "0" and place a multiplier value of .5 or lower like .25 or .1 select the desired morph lets say "grasp" and select down or forward.

It should do a very subtle grasp animation. Try it also on the thumb grasp and spread.

If your animation for example waves his hand. Put the multiplier value to like 5 on the Bend morph so that it will sway with the arm movement.

That's rather clever, Owl - thanks for sharing that!
