Modified Standard shader to start fading based on Camera Y distance

Needed this kind of effect for a small game, where:
– objects below would be faded out
– player can move up and down (fade should “follow”)
– realtime lights should be supported

basically like the old unity global fog for height, but that one doesn’t work with newer unitys.. and shadergraph might have helped to create this effect, but i’m not using new render pipelines..

Without custom lighting in shader, it didn’t work, even with black ambient color, since there are lights in the scene (image below)
