Modding Discussion • Re: How to prevent cobblestone from spawning like this?

I suspect this is an engine problem, because it only happens for some mapblocks. I don't think it should be possible for the cavegen to happen after core.register_on_generated.

You could try to use core.register_mapgen_script(path). https://github.com/luanti-org/luanti/bl ... nvironment

Edit: And maybe changing the num_emerge_threads setting to 1.
