    I'm confused that if the mesh is set to read/write enable off, the mesh collider which references the mesh seems no collision on iOS & Android. However, on Windows the collision is good, no matter read/write enable on or off.

    And turning this on is not user-friendly on mobile platform, so I need to give up using mesh collider?

    PS. the version of unity is 2018.4.0f1

    It seems I know why.
    Base on documentation, if mesh collider's cooking options flags are set to any value other than the default, the model needs to be set read/write enable on.
