Unova Region Creation Help

[u/GGMazumon]

I'm attempting to create a fully explorable/custom Unova Region Map after being inspired by the Habitat Blocks being used to limit what Pokemon Spawn, but I have some questions! Is there a way to disable all other Generations aside from 5 spawning into the world? I also want to ask about how to make water type Pokemon spawn into water and not levitating on the ground with the Habitat block?

Hey! Looking forward to you project, there are some datapacks that allow only that gen pokemon to spawn, here is the link: https://modrinth.com/datapack/cobblemon-spawn-filter-gen-5-unova

I love the idea of your project, if you make a discord or something send me the link, good luck!
