Brow Rigger - Controls don't move joints

Bug
#1

I ran into this issue where I’m able to run the brow rigger but once the brow rig completes non of the bones are moving with the controls. I have tried many solutions to fix this issue but I can’t seem to get the brow rig to complete correctly

I have tried:

  1. Mirrored, R side and L side individually
  2. Made sure Preserve Children is checked and “track selection order” is on
  3. Secondary controllers on or off
  4. “Compute topological autoskin” on and off
  5. Tried several different edge loops for the brows and have avoided 5 point intersections when selecting the edges.

Same result for all

The only warning I get in the script editor is

Warning: Too many coincident knots. Maximum allowed is degree

// Warning: brows_R_mainCtl_upvShape (Nurbs Curve): Tweaks can be undesirable on shapes with history.

My edge look order looks like this.
m_face_geo1Shape.e[2909],
m_face_geo1Shape.e[2929],
m_face_geo1Shape.e[2936],
m_face_geo1Shape.e[2949],
m_face_geo1Shape.e[2956],
m_face_geo1Shape.e[2969],
m_face_geo1Shape.e[2976],
m_face_geo1Shape.e[2987],
m_face_geo1Shape.e[2993],
m_face_geo1Shape.e[8471],
m_face_geo1Shape.e[8473]
,m_face_geo1Shape.e[8659],
m_face_geo1Shape.e[8661],
m_face_geo1Shape.e[8817],
m_face_geo1Shape.e[8819]

Can anyone tell me why the joints aren’t moving with the controls and why this is failing?

What version of mGear? What version of Maya?

Can you share screenshots or gifs that might help show the problem?

And are you sure you aren’t getting any other errors or warnings? They might be happening earlier in the build. Otherwise, you’ll sort of have to trace along the connections and see where the actual break is happening. The bones aren’t following. Is it because the driving curves aren’t following? Or something else? It’s hard to tell yet.
