I only have ic2 as my base for galacticraft, and am trying to figure out how to actually craft stuff (instead of just cheating... =)) Some items seem to display in NEI just fine, and i can craft the simpler stuff. But like rocket fins will not display at all, probably because it uses steel plates (and i don't have UE), nor will the NASA crafting table. Been trying to guess as to what substitutes steel plates, but nothing i have tried seems to work. Also some things display, like the rocket engine, but i can't figure out what to use for heavy duty plating (the recipe for hd plating doesn't display). I would have assumed it was advanced alloy, but no luck. Have not gone through all of them yet, but hopefully getting a clue to plate replacement would get most of them done.
