People have probably answered this question before but I’ve had a hard time grabbing information and knowledge to understand what I even can use from the threads that I’ve read since the questions and answers hasn’t really been aimed to my project specifically.
So I want to try to create some sort of underwater city looking like this:
So for me to achieve that kind of effect I need to mask out a big sphere in the underwater post process material that I got from https://forums.unrealengine.com/community/work-in-progress/17331-community-project-wip-weather-ocean-water-shader.
A kind person helped me out with a few problems I had and then he later explained to me somewhat what I should do to achieve the effect but unfortunately with my lack of knowledge I didn’t really catch up with a lot of things he said, or I did understand the concept, but not how to achieve it, and if I am to experiment with the underwater material I would probably mess everything up and probably cause end of the world etc.
This was his comment:
(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, this 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 this is not desirable, since what you want is to get rid of the underwater effect while inside the dome.)
So I’m asking if someone could assist me further, perhaps add me on Skype or something for chat purposes.
I don’t know how much work it is to mask out a simple sphere form out of a post process material, perhaps it’s not that much to deal with. But I feel like I still need further help with this, because once/if I get this done, then I can continue with everything else on my own. But it is just the post processing and masking that is a new area for me and I’m not exactly a person with the best learning capacity when reading various forums etc.
I just want a clean empty area shaped like a sphere :c
Unless there’s any better solutions out there to achieve this surrounding aquatic effect?
