I am trying to write a mod to make it so that iron is used to make radiators instead of steel. (This is needed because the scenario that I am running need to make coal via hydroponics in order to make steel, and I am trying to warm the greenhouse.) But no matter what I do it doesn't seem to change the recipe. I followed the instructions Guide (Modding) page of the wiki. I copied the PipeBender.xml file from the game, deleted all recipes except the radiator recipe, and changed the quantity of the materials for that recipe. But nothing. Note that I can make mods to change starting supplies fine. So I know the basics of modding. I just can't get recipes to change. Any suggestions or information is greatly appreciated.
