Ok, I think I understand the problem a bit better after seeing your last post, and I'm not sure, but I think I have a solution.

Try this: Backup the conformer cr2, then open it in a text editor, find the definitions (channels) section for the 'neck' actor. Within this actor find the 'twistY head_twisty' channel and delete it, it should look something like this:

             twistY head_twisty<br></br>                  {<br></br>                   name head_twisty<br></br>                    initValue 0<br></br>                 hidden 1<br></br>                    forceLimits 0<br></br>                       min -100000<br></br>                 max 100000<br></br>                  trackingScale 1<br></br>                     keys<br></br>                                {<br></br>                           static  0<br></br>                           k  0  0<br></br>                             }<br></br>                   interpStyleLocked 0<br></br>                 otherActor head:1<br></br>                   matrixActor NULL<br></br>                    center 0 0.62065 -0.0132322<br></br>                 startPt 0.592904<br></br>                    endPt 0.619452<br></br>                      flipped<br></br>                     calcWeights<br></br>                 }

This is not one of the "basic" channels mentioned earlier, so once deleted it should stay deleted. This is the channel that is responsible for twisting the neck when the head is Y rotated. I've never done this operation (Twistectomy?) on a conformer but it should work.

My mind was on the wrong track, because I didn't understand the nature of the problem, and because the graphic showed 'Twist' in the Hierachy Editor, which internaly is the 'rotateY' channel, so I was thinking that the problem was with the rotation of the neck. That's not the problem, the real problem is with the neck twisting (twistY-ing) in response to a rotation of the head. Message edited on: 11/12/2005 10:15
