Experimenting mod
NetherOreOverlay is a client-side Fabric mod for Minecraft 1.21.11 that helps you find ores by predicting nearby ore locations from a world seed and drawing them as colored in-world overlays. This only works in the nether.
Huge thanks to the creator (armi1014) of OreOverLay, without them this mod wouldn't exist.
