    Hey all, I'm adding an edge outline when I intersect objects to help blend things.
    I have a shader that uses the scene depth to find intersections. It works great against opaque objects but I would like to use it on transparent objects. Is there a way to achieve this?

    White = transparent
    Green = Opaque

    It might be possible if you set correct rendering order and enable z-write for these transparent objects.
