Does anyone have any experience with flipping follicles in Maya?
I have a pretty basic ribbon IK setup, with follicles placed along a nurbsSurface which is skinned to the controllers. I’m experiencing some of my follicles flipping at certain frames of an animation in Maya 2018 and 2019. The flipping happens on the same follicle which is at the opposite side of the ribbon too.
The normals of the surface are fine, and stable. The nurbs surface was created through a loft, but the history is deleted. The V spans go from 0 to 4, for what it’s worth.
The only reference I can find to this is this link. It is marked as “solved”, but the solution is entirely specific to the scene: https://forums.autodesk.com/t5/maya-animation-and-rigging/follicles-flipping-in-maya-2016-sp1/td-p/6678494
Is this a bug? I have never experienced this before 2018.
