Hello Rik007,
Environment and detection are indeed extremly important to create a good submarine simulation... And the moon light (and northern lights) was an extremly important factor. So definitely an excellent idea to get this factor work correctly...
I suppose all this works with a fix to the hardcode itself, especially to get the albedo effect? BTW, I'm really happy to have watched your video where you explain what it is, I've learnt something today!
"If people are willing to learn how=to-hard-code-fix I might organize an online workshop."
==> Oh, yes, learning how to hard-code fix would interest me a lot.
"As how to contine: I will ask some people to 'beta-test' and depending on the results further steps will follow."
==> I'm interested.
