Mesh vertices reordered; mesh optimization

Unity Engine
1

My mesh works in 2020.2.2 fine;
In 2022.1.0 some vertices and/or triangles has been reordered by editor.
Result: my mesh ‘broken’ for me.

Should I disable ‘optimize mesh’ in mesh setting to prevent it?
Is it enough for future: 2024…2025…2030…?
Ohter mesh settings?

Why are you using 2022.1.0? At the very least use the latest patch level of 2022.1.x or jump straight to the 2022.3.x LTS version.

If you must keep vertex order, you must turn off all optimizations for mesh import.

And I will stand corrected if incorrect, but AFAIK, mesh optimization is kind of useless now, and adds very little performance anyway, kind of a holdover from days when polycounts mattered a whole lot more than they do now.

In my experience, I saw no loss from turning mesh optimization off, even on huge(256K +) meshes.

(Vertex order is important for my skinned mesh renderers, which are at lod0 about 50,000 verts).

I use 2022.1.16f.

Thank you very much, will try!
