I wrote small addon for TFC to fix crafting problem with mcpc.
Here is recipes i added
ItemStack leather = new ItemStack(TFCItems.TerraLeather,1);
GameRegistry.addRecipe(new ItemStack(Item.helmetLeather), "x ", " ", " ",
'x', leather);
GameRegistry.addRecipe(new ItemStack(Item.plateLeather), " x", " ", " ",
'x', leather);
GameRegistry.addRecipe(new ItemStack(Item.legsLeather), " ", " ", "x ",
'x', leather);
GameRegistry.addRecipe(new ItemStack(Item.bootsLeather), " ", " ", " x",
'x', leather);
Then i tried those in game I was able to craft only two of them - helmet and leggings. But if i put leather in upper or lower right corner - i still get helmet and leggings. How to fix that?
