I’ve been trying to add IK controls to this arm, but I can’t get the hand’s position to be the same as the IK target bone’s position.
I was able to get it to work a little bit, but its not perfect. If I wanted to have the hand parented to something it’s holding like a weapon, it drifts a little. I assume this is because the target bone’s position and hand position aren’t the same. I did try to make the target bone have the same position as the hand, but the tail of the lower arm bone just snaps towards it.
If anybody could help me with this, I will give my life to you 
, it will help me SO much with making the hands look good!
