How to set up IKs with controllers?

**t3h m00kz** · November 27th, 2009 04:38 PM

Not sure which forum this would go in, so I'll just ask here. What steps would I need to take in order to create IK constraints with wrist controllers similar to the ones created with Ctrl Alt Destroy's IK controller setup script?

Just so I know how to do it without relying on the script in case I want to animate with a different bone setup, or a different part of the body.

If you help him on the forums, it'll help people in the future when they search for it!

Alright, finally after dicking around in CAD's script I found out how (i used to know but i forgot)

If it's arms, they cannot be perfectly straight, they have to be bent out of position, so I usually set up my origins with them.

1. Then, create an IKHISolver from the start bone to the endbone. Rename this to whatever, I don't care.

2. Then, create a dummy (helpers>dummy). move it to about where that bone is. Create an orientation constraint the end bone to the dummy.

3. Create what you want to use as your "controller" ie: splines like in CAD's tutorial, or a dummy (however, I have had problems using those as controllers in the past.)

4. Link the dummy and the ik constraint to the controller

5. ???

6 Profit!

You can use this for basically anything, however, i STRONGLY recommend using biped systems for skeletal bodies (people, aliens, such) because they can plant their position and rotation (ik is completely locked, and FK is un-locked) for bones. (if you create a running animation for halo, they dont have to run in place, i'm not sure why peoiple think this)
