Hi,
We’re currently working in Unity 2018.4.4f1 and for the second time in a month a mesh seems to suddenly break between updates without anyone touching the .fbx. Reimporting doesn’t solve it, neither does changing around the import settings.
The left is the broken asset in the scene, the right is when I add in that same mesh anew from the project window. By the looks of it something happens to the vert IDs but I have no idea how. Any ideas what might be the issue?
