Hi guys.

I am doing a tutorial at the moment for practice, and I have come to the part where I need to mirror the geo.

I have done the following to try and fix the issues.

- Snapped all the edge verts to the central axis

- Turned on Merge Verts and Merge with Original

- Played around with the PolyMirror1 node Merge Threshold value

None of this is working. I went over my model and couldn't find any flaws that would create the kind of weirdness I'm seeing when I mirror.

The nose, chin, and underneath where a space for the neck should be, all pull in to one vertex.

An assessment by some more experienced eyes would be really appreciated.

Cheers
