Motion Trail flips skelleton

Hi,

hope someone could help me. I create a spline IK for the spine and enable "Advanced Twist Controls" with Object Rotation Up (Start/End).
By animating my character i want to create a motion trail for my wrist and then my skelleton flips weired. I wondered whats happend, tried MT for the feet and it works, tried it for the head, skelleton flips weired. I figured out, that the skelleton flips every time i create a MT for something thats in hierarchy under the spine (e.g. arms, neck, head) and it only flips if i have enabled Advanced Twist Controls and rotate the spine. It doesnt matter which world up type i use, only if i use relative as world up type i can create a MT which not flips the skelleton, but with relative the twist for the spine dont work.

I tried also to parent or constrain a locator to the wrist and get my motion trail from it, but the skelleton flips again.

I really have no idea whats the matter, i dont understand how a Motion Trail could flip my skelleton, there must a thing i overlooked.

Anyone know that problem or have an idea whats the matter?

I have problems with motion trails flipping, u say tho that ur other MTs do not flip.

If that's true. Duplicate one that works, and then edit the MT for the spline as u want.

But it could e with the orient of ur spine Ik?
