Hello, everyone. First of all, I strongly recommend that you download projects through the official curseforge and modrinth launchers—this will increase the reward for the creators. Thank you all very much for your support!!!
A mod API that allows you to add NBT tags to structures in the overworld during generation, making them physical using Create Aeronautics (Sable).
To avoid generating structures within the mod's API that rely on auxiliary mods, you can use the following command:
/give @s physical_structures:structure_spawner[physical_structures:structure_id="physical_structures:gun6"]
