Polymorph

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.

Features

Crafting

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.

Smelting

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.

Smithing

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.

Commands

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.

ABOUT THIS LISTING

This page describes Polymorph by TheIllusiveC4. The description and screenshots are the author's own, imported from their listing on Modrinth on 24 October 2026: https://modrinth.com/mod/polymorph

Mythiq.net hosts no files for it. The download button goes straight to the release file on cdn.modrinth.com, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

MOD LOADER

This release is built for Forge. A mod built for one loader will not load under another — Fabric mods do not run on Forge, and vice versa.

GAME VERSION

Built for Minecraft 1.20.1, 1.20. Minecraft mods are tied to an exact version: a 1.21.4 build will refuse to load on 1.21.5.

DEPENDENCIES

Check the author's listing for required libraries before you start the game — a missing dependency shows up as a crash on launch, not as a warning.

1. Install Forge for the Minecraft version you play, if you have not already.

2. Download the .jar with the button on this page. Do not unzip it — a mod jar is installed as it is.

3. Put it in your mods folder:

Windows — %APPDATA%\.minecraft\mods

macOS — ~/Library/Application Support/minecraft/mods

Linux — ~/.minecraft/mods

4. Launch the game with the Forge profile selected.

ON A SERVER

Anything that changes world generation or gameplay has to be installed on the server as well as on every client. Client-side visual and interface mods do not.

UPDATING

Replace the old .jar rather than adding the new one beside it. Two versions of the same mod in the folder is a crash on launch.
