Parenting a Both Hands to a Prop

I've been playing around with RiverSoftArt's Bone Doctor which allows the pose to be intensified or relaxed.  But the problem is that my character has both hands on a big axe in the starting pose and i want him to keep his hands on the axe.  Is there a way to lock/parent/something so both arms and axe move in concert?  It's just too tedious to have to keep repositioning the second hand.

    To complicate things further, I just parented the axe to the left hand so I could reposition the right hand without moving the axe.... and it repositioned the axe anyway and it's NOT where the left hand was holding it.

    Next, I tried to memorize the object's pose before parenting to the left hand.  But restoring the pose doesn't set it to the position it was at when it was memorized. The parameters are set exactly the same but it's some other random location.

    Are there any tutorials/explanations on how parenting works and what it's based on?  It seems all very random to me but obviously there are some hidden rules involved.  Also about positioning props.  Logically, not just dragging them around until it looks right.

    Casual, I think, has a script to help with the two hands thing - sadly DS doesn't (currently, at least) have parentable IK targets which is what you need here.

    Having the same parametrs won't work as they are offsets from the hand, and of course they will not be the same for both hands. Do you have Parent In Place turned on when you reparent the axe - it's a check box in the dialogue, or a checkable menu item in the Scene pane option menu?

    I think the script you might want is https://sites.google.com/site/mcasualsdazscripts6/mcjautolimb2015

    using it, you can create a null parented to your prop, and then the script will adjust the hand in each frame to keep it where the null is located. So you can parent the prop to one hand, parent the null to the prop (positioned appropriately) and then let the script adjust the non-prop hand in each frame.

    Good luck!

    Ah!  I missed that check box.  That fixed the left hand problem.  I'll check out that script and see if it will work to keep both hands on the axe.  Thanks, y'all.
