I've been working on a cross over mod for some time now, even before people started talking about it. It's gonna take a long time figuring out what materials are necessary to add to tfc world gen,but I have a good bit done.
Let's see, we've got...
- Iron(Hematite, Limonite, Magnetite)
- Copper(Malachite, Native Copper, Tetrahedrite)
- Gold(Native Gold)
- Silver(Native Silver)
- Platinum(Native Platinum)
- Coal(Bituminous Coal, Lignite)
- Redstone(Cinnabar, Cryolite)
- Lapis, Saltpeter, Sulfur, Graphite
- Other Gems (Ruby, Sapphire, etc)
- Aluminium, Silicon(Kaolinite)
- Sodium, Boron(Borax)
What's missing...I can only think of Neodymium, Tungsten, Titanium, and Iridium.
