    Ran into this issue while making some eyecandy for a WebGL project. Even made a minimal repro and filed a proper bug report, but it turned out to be a duplicate.
    I really want this fixed for a ground fog effect, it just looks bad when intersecting with walls.
    Unity plos, I'm begging for a fix.
