I haven't played in a while. Since 1.8 I think. Or 1.7. I just tried making some shears and the recipe seems different. More importantly it now looks like it takes 2 Ingots instead of 1, which seems rather expensive. There technically are enough metal "pixels" to do the whole blueprint, but I can't push the pixels on the lowest plane, so I can't get the last five or so pixels of the blueprint. Am I forgetting something about the smithing mechanics?
Edit: I don't quite yet get why I could push the bottom layer pixels in one direction unto the 2nd layer, but not a different direction, but I managed to make it work now. Guess I was just rusty.
