This is an updated version of my old "Many More Structures" Mod, which due to changes made in 1.20 to the underlying structure generation of Minecraft, required a complete rewrite.
For versions 1.18.2 and 1.19.2 do to: Many More Structures (Prior... - Mods - Minecraft - CurseForge
With this mod installed and with the config set to anything more than 1, many more of all the vanilla structures will generate.
And by more, I mean that at level 5 there is almost no ground in places. And the end is hard to fly through due to the cities.
Though at level 5 your world will also be nay unpassable due to the structure count. So, I recommend only going to level 4.
I highly recommend using a Pre-generation mod while using this one. I have found that "Worldgen" by caeruleusDraconis works really well. It can be found here: WorldGen - Mods - Minecraft - CurseForge
