OresDimensión Add-on 1.21+/1.20+

You no longer need to specifically return to the normal world of Minecraft Pocket Edition, just to collect resources for subsequent exploration of The End or the Nether. The Mod OresDimensión will allow ores to be generated both in the Nether and in the habitat of the Ender Dragon.

All types of ores, starting from coal and ending with emerald, can be found in the dimension of the Nether or the End. This will make resource extraction a bit simpler, as you can assemble materials literally throughout the universe.
