    Hello!
    I try to upgrade a project from Unity 2018.3 to 2019.2 and there are some issues with cloth physics.
    1. Cloth constraints are misplaced (see attachment). I can fix them manually, it seems it is connected with mesh optimization.
    2. Vertex movements became too intensive and chaotic.
    3. Gravity influence seems to be wrong. Cloth vertexes are far from other colliders and looks like they gravitate along x or z axis.

    I hope somebody has already faced this problem before.

    1. That's documented in this thread.
    2. Experiencing stretching or distortion? Right now there's a couple of serious issues that relate to mesh density which I documented in the same thread.
    3. That was an issue for a long time, finally fixed in Unity 2019.2.6f1. I think that was also the source of some of the chaotic movement I got. I have more info about it here and it's possible it's not fully fixed.
