Can I lock 1 figures hand to say, another figures ankle?
so when I move one figure it will traslate to another figure.

eg, I move one figures arm and it pulls on the ankle of another?
any help would be great.
Thanks

not sure what you want to do. if you want to  have a characters arm move around and follow a characters leg while holding  the characters ankle   say their right hand, just go to figures and then IK and turn on the right hand IK. After that when you move the other character's leg the  hand will stay  on the ankle but may require tweaking if you move it too much.

now if you just want to be able to move 2 characters by moveing one   parent the characters hand to the other characters shin and you can mobe the  grabed character and the grabber can go along for the ride.

  1. Put hand on ankle.
  2. Parent the hand to the ankle,.
  3. Turn IK  ON for the arm the hand is a part of. 
  4. Possibly do a chain break at the shulder.
  5. Check manuel (if necessary) on how to parent, and what IK is.

I think I get it, but when I parent to the ankle,, my first character turns all upside down and is rotated. lol

Uncheck  the 'Copy Morphs'  or whatever when parenting.

yeah, Inherit bends or something like that? I did that.

If that doesn't help, click 'Body' (not Hip) and rotate figure back around.

I also try to set parent from the properties on the peramiter dials window, and the set parent is ghosted out. I can't click it.

Start from scratch, and zero each figure before posing, and see what happens.

sorry man, Zero? what do you mean by that?

Meun Bar at top:
Windows / Joint Editor / Zero Figure.
Make sure that you select a figure before trying to zero it.

Thanks for your help man, but I'm pretty sure now that you can't set a parent for just a hand,

what I want to do is,, have a guy hanging another guy off a building by his ankles. so I want figure A to have his right hand on figure B's left ankle and vice versa for the other hand and ankle.  so when I move the arms individually, it will move the legs its attached to. ya know?

so if he shakes his arm, the shake translates to the leg. I hope ya know what I mean, lol

Read these four tutorials by Dr. Geep, they should give you a better idea of what you need to do.

The only way I have managed to do something similar is to use a primitive, I find a ball to be best scaled to about 20%. Move the ball to the ankle and parent it to the ankle. Pose the figures and then select the forearm and get it to Point At the ball. When the first figure's leg moves the forearm will follow but you will need to adjust the hand position accordingly. If you point the hand to the ball, only the hand will move and not the forearm. IK needs to be off. Keep the ball visible until you are happy with the result , then you can turn visibility off. Wish there was an easier way but this is the closest I'vee come so far.

Lol, I tried the ball thing too, haha but the problem comes again with setting parents. you can't set two parents for one figure,, IE 1 ball per hand and ankle. I'm gonna check out the above tutorials in a bit. thanks all.

give it a try and let us know, munky. but I am trying to imagine the nightmarish figure distortions that would arise when the parent figure has feet IK on, and the child figure has hands IK on, or any permutations of the above.

It can be done. But you have to be sure about the "master" and the "slave". 

First, make sure all inverse kinematic settings are OFF. (Figure menu->Use inverse kinematics).

If you want to animate the arm that holds the ankle, that arm will be the master, and the ankle will be the slave. But if you want to have the topmost guy kick his feet, and have the arms of the guy hanging below follow the movement of the feet, the legs/feet are the master.

You have to turn on inverse kinematics for the "slave". In your example for the leg that the hand holds on to.
Then parent the foot (end of the IK chain) to the hand.

The order is important: first enable inverse kinematics for the leg, then parent the foot to the hand. It won't work the other way around.

This is more of the difficult area for my poser skills, because I haven't dealt with it. but where do I set Master and Slave?

I really appreciate all of your help guys. you rock.

Glad someone who knows a whole lot more than me came along lol

Actually, you don't set Master and Slave.

Let me try to describe the situation.

The hands of Figure A grab the ankles of Figure B.
You want to pose the hands/arms of Figure A, and you want the ankles/legs of B to automatically follow the movement of Figure A's hands.
That's why I call the arms of Figure A the masters, and the legs of Figure B the slaves. When a master moves, its slave must follow.

To set up the "master-slave" relation, you should do the following:

Now you can move the hands/arms of Figure A and the feet/legs of Figure B will automatically follow the movement.

Hope this is somewhat clearer.
