    I have an asset processor pipeline taking multiple FBX and merging them as blendshapes into a single

    When the mesh is re-generated, I first obtain a broken mesh with triangles scattered around. It looks like the triangle positions are good, only some of them are visible:


    When I restart Unity, the mesh re-appears correctly and all triangles are visible:


    My processing hasn't changed and the algorithm is correct. It looks like for some reason the mesh appears broken but the topology might actually be perfectly correct (hence a restart fixing something).

    I was previously using Unity 2020.2.6f1 where I never experienced this issue.
