MeshCollider from >65k verts

    It seems to me like calling 
    MeshCollider.Create()
    with a very large number of verts (most likely >65k since that's where the UInt32 indexing would kick in) never resolves - is this a known issue/limitation of the current Physics preview?

    EDIT: I take it back, looks it works (reasonably quickly) on 120k verts, but chokes (or takes an inordinate amount of time) at ~390k.

    EDIT AGAIN:
    Further investigation has led me to believe this might actually be due to the mesh having orphaned triangles. Gonna experiment further and see if I can isolate the issue.

    Did you figure this one out? I was getting super slow results from this function on very small meshes. For 1961 triangles in triangle soup.

    Weld @ 65ms, DominantGeo @ 20ms, BVH @ 32ms and some 18ms for the rest of the function

    I believe the answer is simply "this isn't optimised yet" unfortunately
