View Full Version : Orient constraint mangling rig

03 March 2003, 04:51 AM
Hi, guys

I'm rigging trying to constrain a control curve to my rigs root joint. The point constraint goes on fine, but when I orient constrain; the spine rotates 180 degrees. I remember reading somewhere that you can somehow duplicate and panet a joint somehow to fix the constraint problem. But I haven't a clue on how to actually do it. :shrug:

Anyway, anything in the way of help would be much appreciated.

Why not just parent the curve to the joint. Is there really anything above your root joint (other than maybe a locator)?

but to solve your problem.... the quick and dirty way is. Find out exactly what's rotating (and how much). Then when you orient constrain, use the "-o float float float".

something like below

orientConstraint -weight 1 -o 180 0 0;

Good Luck!

What I usualy do is go into component mode select the joint and rotate, its much easier. Also when you rig is verry important that you zero out all your joints before any kind of constraints or parenting.

what i usually do is create a locator and point and orient constrain it to the joint in question. then, i break connection on the locator, then orient constrain the joint to the locator. then i go make the locator a child of whatever nurbs curve i want to control the joint with.

its probably a lot of work for a simple result, but hey, it works. :airguitar

Thanks Guys! :beer:

I solved the problem but thanks for the info, I should have thought of some of at least one of those. Case of target fixation I guess. :shrug:
