why is there a lack of anything generating underneath like resources, you would think that it would have resources. even enabled random generations thru game editing

Resources are generated (currently mirrored in level 1 from the top surface), I'm still open for ideas what to include

they never mirrored for me underground

Do you have other mods installed?

Did you ever figure this out? I currently added this mod to a in progress save (incase that's the issue) and it's empty I used the ping feature and belted up to surface right under a coal vein and there is nothing here.... ??

Oddly enough I just found copper on a drained vein and uranium but not the coal veins lol

volcanus seems to just be empty there isn't anything under I went under cal, coal, and tung and nothing in any

Everything works for me even with the mod added to a save. Please send me your savegame (saved without the DLC).

If you run the command
/c game.print(serpent.line(game.player.surface.map_gen_settings.autoplace_controls))
you see the autoplace parameters that are used for generation. The map seed stays the same
