this has been known a long time, as long as the item you create is in the proper location in your dev kit and not in the directory your mod is in it will cook referencing that item in the other mod folder in your dev kit and when it loads in the game it will take the other mods version of the item because the one you have in the dev kit wasn’t cooked with your mod since its in another directory structure. so if your mod is mod/somemod and thiers is mod/thiermod and you make a new mod folder in your mods folder called theirmod and copy the directory structer and naming completely identical you can cook it for use in game.
