To cut a sphere shape from the post process “material” it is always possible to mask it inside that material. The best way to do it is using distance fields where you would put an invisible sphere covering what you want and get the value from distance field from it and subtract in the material from the effect, leaving a completely clean area… So far, subtraction would need to occur only when the camera is inside the sphere, otherwise you would be seeing a hole (of half a hole when you have a dome) where the city is and is not desirable, since what you want is to get rid of the underwater effect while inside the dome.
I dont have anything ready for , but Im sure you will be able to accomplish if you do the research… there is such effect in a tutorial somewhere in the internet.
You could give me a year of research and you would still find it out before me within 5 minutes, but I’ll do my best and check the internet… I just know that I’m terribly bad at it
