Shape key mirror, oh my god !!!

I’m following a tutorial on creating and rigging a character, and I’ve hit a wall with mirroring shape keys.

Basically, when I attempt to mirror shape keys (on the eye lids), I get an error that some of the vertices failed, e.g. “0 vertices mirrored, 171 failed.”

Here’s how I’m attempting to mirror the shape keys:

STEPS

  • set the influence of the shape key I’m mirroring to 1, and all other shape keys to 0
  • with my shape key selected, “New Shape From Mix”
  • with the new shape key selected “Mirror Shape Key” (also tried “Mirror Shape Key Topology”, same problem)

EXPECTED

New shape key should mirror the old one
ACTUAL

After error, “0 vertices mirrored, 171 failed”, new shape key is mosty mirrored correctly, but applying it affects a mix of vertices on the left and right eyes.

I’ve used Lattice instrument to modify the mesh working simmetrically on both side.

Please i don’t know how going on, help me.

Thanks

Are yo 100% confident that your mesh is perfectly symmetrical
Have you tried disabling the lattice modifier
Supply a link to your blend file for review

Hi Richard, this morning i’ve newly tried, but it fail yet.

Thank you.

The object is not symmetrical.

Use the Mesh / Symmetrize option before you start doing anything with shapekeys


Thank you so much !!!
