wing rig complications

So I’ve got this dragon model I’m rigging, but I’m having some difficulties in figuring out the best way to rig the first and second of the finger bones. http://fc08.deviantart.net/fs70/i/2014/277/d/1/halp_by_jaderavenwing-d81lqoa.png

They’re supposed to slide along each other like this: http://fc04.deviantart.net/fs70/f/2014/277/2/7/wing_by_jaderavenwing-d81lqp7.jpg

I’ve tried a couple of different things, but the bones always end up moving inside of each other which is no good.

Any suggestions?

What do you mean? Only way bone setup will fail for this setup is when fingertip bones crosses each other. Here is the picture of rig that shows fingertip bones touching. But this happens when bones are displayed in Octahedron. Bones don’t touch in Stick display.

The rig is setup so that IK constraint is on CC bone to look at IK target. The bone C simply have Damped Track constraint to point to IK target. The IK constraint applies to bones CC, BB, AA. The rotation of those bones are copied from BB to B and AA to A.

thats what i was thanking
damped tracking, Track too, and limit distance.
then adjust to what you need

Is there any way to do this, or something similar, with just FK rigging? If not I’ll just have to manually make sure everything lines up properly! Thank you guys though. I appreciate time taken to help. :slight_smile:
