How to make underwater world outside the window?

[UnrealFreak]

Hello everyone!
I have an underwater location where we are in an underwater laboratory. We need to make an underwater world outside the window. I found a very beautiful blueprint of the underwater world, but I do not know how to make it work only outside the building (I attach a link to the blueprint). There is an option not to use this blueprint, but I have not found anywhere lessons on creating water as an underwater landscape - if you have similar ones, please share, or help to sort out the existing blueprint.

Usually, that ‘underwater look’ is accomplished using a post process. Trouble is, you have to be in the PP volume for it to work.

Unless, you write the PP material so that it can be viewed from the outside.

So, underwater PP

and viewing from the outside ( or localized PP as it’s called )
