Will it be compatible with the William Wythers or Terralith data pack?

I'd love to make custom structures but haven't looked into how it works.

There are some guides on PMC or on Youtube, I remember I watched one recently.

Nooo... I already work with William :) I don't need more work. Also, currently we have a system in WWOO which allows us not to update the add ons when the base pack gets an update. With this project, it would be problematic for me, to update all the things every time the update drops. So, no add ons. At least until I get an idea for one :P

Hi! This is a pretty cool pack! However, I have a two suggestions:

1. Split up the chasm_world_settings file into a dimension file, dimension type, and noise settings file so that you dont have to import settings

2. Switch from a checkerboard biome layout to a multi noise layout, it may seem intimidating at first, but you'll get the hang of it

Also, I'd recommend joining worldgen related discords like the Terralith discord (owned by Starmute) or the Dimensions Initiative server

also, incase you havent used this: https://misode.github.io/worldgen/
its very useful for learning how types of things work, and having easy access to vanilla code
