Schrödinger's Ingredient(Dummy Cat)
Schrödinger's Ingredient adds a dummy cat item that stands in for an empty slot in shaped crafting recipes on Forge for 1.20.1.
What it does
A placeholder ingredient fills an empty slot in a shaped recipe, so the pattern still matches when a machine or player leaves that slot blank. Once the crafting completes, the cat is consumed and disappears from the grid, leaving no residue behind. The mod is built around automated setups: an automation system can place the cat where a recipe needs a gap, and Create's Mechanical Crafter can then process complex shaped patterns correctly. Compact setups can use it to process quantum voids recipes as well.
Installation is needed on the client and on the server, since the environment is client and server. The optional PackagedAuto dependency is named for the automation use case, and the mod is released under the MIT License, though it is not open source. Files exist for Forge 1.20.1 only, with version 1.0.0 published on 2025-10-25.
Key features
Placeholder crafting ingredient
A special cat item fills empty slots in shape-based recipes so the pattern matches without a real ingredient.
Consumed after crafting
The cat disappears completely once the craft finishes and is never placed in the first slot of the grid.
Mechanical Crafter patterns
Shaped recipes with gaps can be processed by Create's Mechanical Crafter, which accepts the dummy as a filler.
Quantum void setups
Compact automation builds can use the cat to process recipes that involve quantum voids.

What the author says
This mod adds a special cat that is "not observable" to shaped crafting recipes. Once the crafting is completed, it disappears completely. ...And that's it. What exactly is the purpose of this seemingly pointless mod?
