[1.19.2] Is there a way to delete dimensions?

[TheElementGuy]

I have a mod and want to delete the Nether to replace it with the Underworld from Greek mythology. Is this possible? If not is it possible to replace the Nether generation so that it is basically just the Underworld?

You do that with datapacks. Your mod is a datapack

 

I would recommend you do it as a new world preset (like large biomes or amplified) rather than unconditionally overwriting the nether.

e.g. this is botania (garden of glass) preset that overrides the overworld to be "botania:skyblock"

You would instead override the nether to be your generator

Okay! Thanks.
