Warning: Cycle on `JNT.parentInverseMatrix[0]` may not evaluate as expected.

Hi everyone,

I have created IK FK and Result Spine Joints. I want to make a twist, using IK spline Handle and skin the CRV to 2 Bind Joints. But it appears this message: 

Warning: Cycle on `JNT.parentInverseMatrix[0]` may not evaluate as expected. (Use `cycleCheck-e off` to disable this warning.)

Does has anyone any idea that could help?

Thank you

It sounds like you're trying to bind the ik spine joints to the ik curve? That would create a cycle: ik curve -->Joints-->ik curve.

Generally you would create some separate "guide" joints and bind the curve to those, then use your controllers to move the "guide" joints.

Hope that helps!

Thank you for your response.

Well , I created I result skeleton( for the spine), ik spine handle and  2 Bind Joints, start and end, that  I skin the CRV on them. All to make the spine able to twist.

In addition, I created an IK and a FK skeleton. 

Now, I try to figure out, how do the parenting between the FK, IK and the result Joints.

Any recommendation please?
