About Sky Islands Dimension
From ModrinthAdds a New Dimension like the overworld with a fancy sky islands generator
Basics
Adds a new Sky Islands Dimension that has overworld biomes, structures and features.
_Not a 1 to 1 match with the overworld as ocean and river biomes have been replaced with other biomes since they don't work so well in a sky islands setting_.
Terrablender biomes place and function in this dimension too!
Important Info
There is no built-in way to get to the dimension in survival mode! I recommend using the Datapack Portals mod to make a custom datapack portal that takes you to this dimension.
The Dimension's namespace is "skydim:overworld".
You can use the execute command to get there without Datapack Portals.
I highly recommend a datapack that extends the world height since the top of the skylands is about at default build limit! If the datapack extends the overworld height, it will also work on this dimension.
Weather works normally but the weather command can only be executed in the default overworld! Time and Weather sync with the Default overworld.
It can get very dark in the lower parts of this dimension and due to how the dimension works, lower layers won't usually have features placed on them. Bring torches and prepare to fight lots of monsters.
Usage in Modpacks
You are more than welcome to use this datapack/mod in your modpacks, just credit me if the modpack is public! A Note for Modpack Authors: You might have to configure some of your mods to have them accept this as an overworld-like dimension.
