There is a lot of dungeon mods at fantasy or vanilla style but not so many for tech modpacks. It's a compilation of industrial, post apocalyptic and sci-fi structures. I hope the original author doesn't mind using his mod as a basis :/
No changes could be made to the code, in fact it is the same Ruins Mod. Therefore, I cannot correct or change the things done by the author. And also transfer the pack to those versions of minecraft for which there is no Ruins Mod.
I am waiting for Ruins for version 1.16.5. Until it is updated, my structures cannot be made for 1.16.5.
The new version of the pack uses blocks from Chisel. This fixes the iron balance and makes the structures as they should be by design. For those who do not want to install Chisel, the old version is available.
For those who are not installing for the first time: when installing new versions, you need to delete the ruins_config folder from .minecraft\config. Otherwise, structures from old versions will be generated.
