I'm working on a skyblock world, and I am wondering how to generate the nether as a complete void with no blocks, I still want to keep the biomes and structures, just remove all blocks, I also want to do this with the end.
For the overworld it's easy to do this, you just generate a super flat world with 1 layer air, but this wouldn't work either, since I want structures, but no blocks, so if I generate a world with structures, there would be floating villages and such, but I don't want that, I only want the structures to remain, so you could build witch farms and such
As SF. said, i could use the quickcarpet skyblock mod, and it was available for 1.16
