out of curiosity, are you expanding this mod to include the Small and Normal map sizes aswell?
(ported into smaller maps, but needs testing to see if they work, I just scaled down other maps on the 3rd file, give feedback if it works or not )
I slightly enlarged them and made "sea" level at 55%+, it should work, but not necessarily, so I need feedback on it if you test "Large maps" and below. Look at the XML file, and tweak the values if possible, my values are just a suggestion not necessarily perfect
It's easy to tweak the files to get that "perfect" level, so just experiment and get back to me. Hopefully the XML file should be easy to edit and test, so if you get a better one, PM me, and I will update ^^
