And idea what is going on with this mesh and how to fix it? I am importing .obj files with shapediver import plugin. And all of them are invalid but mesh join unify and clean usually resolves it. But there is a one or two meshes that are not affected by this fix.
Here is an example one: invalid mesh.gh (112.7 KB)
Thank you for your help in advance!
Edit: As a matter of fact mesh join alone usually fixes it.
