The guide that you've provided states that for versions after 1.19.2 require a biome.json file so I just want to make sure that I have it right. So in the example it goes data/atmospheric/separated_leaves and then inside that folder would be where the biomes.json file goes alongside the morado.json, right? And you only need one biome.json file for each mod or for every tree json file that's added?

I'm new to this, just want to be sure ^-^

Okay, thanks so much!

Only one per mod/namespace :)
