I would like this as well please, add copper to the ores that this mod already has spawn on earth start. This allows hydrogen to get you to space, then distribute the other ores IO adds to whatever other planet you want. having said that i don't know how coding and all that works so maybe its nearly impossible to get the two mods to "talk" to each other.

I'm not familiar with Industrial Overhaul, but the ore distribution for each planet is defined in an XML file. It should not be too difficult to make a Scarce Resource for Industrial Overhaul mod if anyone wants to do it. I have no plans to do so myself but I don't mind if anyone wants to make clones of this mod.

Love the idea too! I'm playing IO, and as soon as I heard this, I rushed over to see if it could work!
Great idea for the mod!

Just in case it's really easy, do you know of any resources that explain custom planets and ore distribution modding in a simple way?
