The Unimesh is an improvement over the P4 hand mesh. But, as moochie infers, it still leaves a lot to be desired. Even the Mill 3 hand will not allow all fingers to touch, as in a salute, without really distorting the look of the hand. And yes, the thumb movement is fairly crude. But, I did the best with what I had. Hopefully the next mesh will be gentler on the hands...
