An extremely simple datapack aimed at disabling world generation of the "spooky" blocks offered by the Horror Elements mod.
I'm glad you asked. Horror Elements mod lacks a configuration file, so you can't disable the absurdly high rate generation of features. Since some mods or modpacks (like ChaosZPack or Cave Horror Project) require it, I had to find a workaround instead of removing it directly.
You (obviously) need the Horror Elements mod by predator97427fr.
