I would like to be able to disable Nickel drops from Limonite, so I can use it purely as a larger source of iron. 👍

Just disable limonite and increase hematite, the result is the same.

Aren't they generated at two separate heights and separate sizes?
It follows the logic from copper and tin deposits too then. Hmm 😢

If you don’t have nickel in your pack it sounds like you don’t really need azurite or Teallite either; sounds small enough that you can make do with only having one variant of mineral per ingot.

Will you accept a PR?
And not having variants at different heights would leave the underground quite bare.

Not really. The reason I'm opposed to your idea is because it Geologically does not make sense, not because I'm too lazy or because it's hard to do.

And not having variants at different heights would leave the underground quite bare.

If you properly modify the configs, then it wouldn't; just ramp up the deposit sizes and you'd see it fill out the gaps :)

Oh fair enough. I will play around with it. What mods use nickel?

Oh, I may reconsider IE. Thanks again! :)

Most popularly, the CoFH mods (like Thermal Expansion) and Immersive Engineering.

Also, there is this :)
