So this isn't really like a "the game crashes" or "something doesn't work" type of problem, but it is regarding adding a mod.
I already am playing on a modded survival world for quite some time now, but now I want to add some new mods. The problem is that the new mods I want add new ores and/or other worldgen features (but mainly ores). Because the world already exists, after I add on the new mods, Minecraft will only generate their ores in chunks I haven't loaded yet. But since I've already loaded a massive area of chunks, I don't want to have to go 10000 block just to find the new ores.
So is there any way to make the new ores spawn in loaded chunks? Any method including commands, writing a mod, editing existing mods, etc. will work.
EDIT: Also don't say "use oredict with your existing mods".
