polymorph but it's for fabric only but also for 1.21.10
by nnmrts
Polymorph, a Fabric mod by nnmrts, lets players pick between several outputs when recipes share the same ingredients.
What it does
A button appears above the output slot whenever the current inputs fit more than one recipe. Pressing it opens a list of the possible results, and choosing one changes the crafting or smelting output to match. The selection is remembered for as long as the ingredients stay the same, and it is saved with the block itself so it persists across world loading and unloading.
The mod addresses recipe conflicts, which become common once many mods are installed. Instead of removing recipes or writing datapacks to keep every recipe unique, Polymorph lets crafting and smelting recipes coexist. A command helps identify potential conflicts, listing recipes that conflict with other outputs in a log file in the logs folder.
The mod is Fabric only. Installation covers the server and each player's game. This version is an unofficial fork of IllusiveSoulworks' Polymorph, updated for Minecraft 1.21.10, and is released under the GNU Lesser General Public License v3.0 or later, which makes it open source. Files are published for 1.21.10 only.
Key features
Output selection button
A button above the output slot lists every result that matches the current ingredients.
Remembered choice
The chosen result is kept while the ingredients stay the same, so repeated crafts use it again.
Saved per block
The selection is stored with the block, so it survives leaving and reloading the world.
Smelting support
Valid smelting inputs that match several outputs get the same selection button as crafting.
Conflict command
A command lists recipes that share inputs with other outputs and writes the results to a log file.
