Polymorph is a mod that solves recipe conflicts by letting players choose between all potential outputs shared by the same ingredients.

With a sufficiently large amount of mods, recipe conflicts are a common occurrence and the responsibility for resolving these usually falls on the user or modpack developer, using datapacks or other tools to ensure that each recipe is unique.

Polymorph offers an alternative solution, allowing all possible crafting and smelting recipes to co-exist regardless of conflicts.



When a group of ingredients matches more than one recipe, a button will appear above the output slot. Pushing this button will show a list of all possible results and selecting one will change the crafting output to match. Polymorph will also remember the last selection as long as the ingredients don't change, so repeated crafting actions are possible on the same selection.


When a valid input matches more than one output, a button will appear above the output slot. Pushing this button will show a list of all possible results with the currently selected result highlighted in green. Selecting one of the listed results will change the smelting output to match. This selection will be saved to the block itself and persist across world loading and unloading.


Exactly like the crafting screen, a button will appear above the output slot when a valid input matches more than one output. Upon selection, the output will change to match.


To assist identifying potential conflicts, there's a command /polymorph conflicts that will try to identify recipes that conflict with each other and outputs a list of them to your logs folder. Currently, the command will scan crafting, smelting, blasting, smoking, and smithing recipes.

Mod Integration

Just Enough Items

Upon selecting a recipe to transfer from the Just Enough Item screen, the output will automatically change to match the selection if there is more than one possible output.

Modded Support

Many crafting tables that are simply variants of the vanilla crafting table will automatically be compatible. Other types of support may or may not be compatible; below is a list of all mods that Polymorph has specific integration with and has already been tested for functionality.
