I'm working with a low poly game model, and I need to fix some vertices that are symmetric by design, but somehow were made imperceptibly asymmetric by rounding error or something.
I need to fix that asymmetry so I can use tools like Select Mirror and so I have the ability to mirror shape keys.
The mesh has some intentionally asymmetric aspects in texture mapping and geometry, so I can't just delete half the model and apply a mirror modifier. Also the model is rigged and I don't want to lose the bone weights.
Is there a way to broadly fix the asymmetric vertex positions in a vertex selection?
The only way I've found to fix it by hand only works with one vertex pair at a time:
- Select both vertices
- Hit s Shift+x 0 Enter to eliminate Y+Z variation.
- Set the median X coordinate to 0 in the Transform Properties
This works for single vertices, but I need to clean up 562 such verts, so doing it one at a time is out of the question.
