Skaface443 Check it out: nosurfacemonsters

I haven't tested it, but I believe it works :)

any chance for a 1.21 update? 

Seems like 1.21 broke something with the mod (and all others I've tested.) Drifter, Bowtorn and Shivers spawn still spawn above ground :(

Kaeviel I think it's possible, but it would require listing the exact IDs of all the blocks along with all their types that the mob doesn't spawn on.

Perhaps it is possible to enter some command or code that would block mobs from appearing on blocks placed by the player, but I can't do it.

This is definitely a great mod if you only want to deal with monsters underground. Would there perhaps be a chance of just preventing monsters from spawning in areas with non-natural materials (hard-packed dirt, cobblestone, etc)? Ever since the Natural Spawns seemed to stop working, I've been on the lookout for something similar.

LeuxSeveN No problem, I was just curious how to disable their spawn in 1.20.

thank you ^^
