Physics.queriesHitBackfaces does not work with Collider.Raycast



To reproduce:

4. Select in Hierarchy "Target" object, and set it's X rotation to 0.
5. Now press on the white square in Game window. You get Console Debug.Log message.

    This still doesn't work in Unity 2018.2

    I need a way to count the collision in and out points of a ray going through colliders.

    Will that be fixed in earlier versions, too? Like 5.5.x ? Thanks
