About
Kopernicus is a KSP add-on that allows for modification of stock planets and the creation of new planets via modification of the system prefab. Why is this advantageous you might ask? Previous planet adder mods, such as Planet Factory, modified the live planetary system and had to keep multiple hacks actively running to provide these worlds. We strive to provide the least hacky solution by introducing planets into the game in the exact same manner Squad would.
Uhm, thinking about it.. How would I place the tweak from @SkyRex94 into a MM patch? I know how to MM-patch, but since the example would add it to every body and Kopernicus is a complex beast I'm wondering "Which bodies do I need to filter out?". I'm not fond of directly editing files for specific bodies, hence the MM-patch question.
Edit: Here's a patch that adds oceans to non-ocean bodies. You may get contracts for stuff like "splashing down in the Mun's Oceans" but you can ignore those,
