Head/Neck Warping While Walking If Not Independent

I'm having an issue in Character Animator whereby the head/neck of my puppet warps when I try to use the walk behavior. If I make the head warp independent, then it stops warping, and the walk behavior works as expected. But when the head is warp independent, it detaches itself from the body whenever I use camera input. Here is a video that demonstrates the issue:

Any help resolving this is greatly appreciated!

Thank you

    Hi guys, so was this issue resolved? I was able to replicate it with a puppet I built from scratch. I experimented for a while, but I can see that it seems like an either/or issue. What ended up being the fix? Or are we still working on it?


    Yes, Dave helped me resolve it. The fix seemed to be tagging the "head" tag ALSO as the "neck" tag, which seemed weird to me, but it works. Also the waist and hip tags needed to be on the Body group rather than on a layer in the Body group as I had it (although I had tried them on the Body group before sending to Dave and had the same issue, so I think the main thing was the head/neck tag).

    Hello fellow Andy! So, it's hard to be sure from the quick look in the video, but my guess is that your problem has to do with the independence of some of the groups inside your head group. It looks like CH is trying to move the entire head during your walk behavior, but something independent (maybe the nose) isn't allowing the head to move freely and so it causes the warp. Also, on all of your independent layers/groups such as the pupils and eyebrows be sure that the attach style in your properties panel is set to "free."

    I'm pretty sure that's why making the whole head group independent fixes the problem, because it overrides the independent group that's causing that facial warp. If you find the independent layer that is "welded" or "hinged" in place (referring to the properties panel) and correct it, CH should let you use the face behavior to warp with the neck and body WITHOUT causing that unwanted warping while walking.

    Hope this helps and happy animating!

    Thank you for your response!

    I tried setting the attach style of all the independent layers/groups in the Head group to "Free", and this produced no change. Just as a test, I tried turning warp independence off for *everything* in the Head group, and this seemed to have only made things worse.

    Do you have any other ideas as to what I might try? Or is there any other information I can provide that would help diagnose the problem?

    Thanks again!

    Checking out the rig view at :20, I think you want independence on "Zoe" and "Front Right View". Does that solve it?
