Origins x Chest Cavity Compat

by OopsATypo

Origins x Chest Cavity Compat is a Fabric compatibility add-on that keeps Origins powers and Chest Cavity organs from clashing when both are installed together.

FabricClient and serverAll rights reserved1.20.1

What it does

Origins and Chest Cavity both alter what a player's body does, and some Origins powers conflict with organs that Chest Cavity already provides. This mod does not replace the chest cavity system. It removes only the specific origin powers that duplicate or contradict a Chest Cavity organ, so the organ can take over that function. For example, the merling origin's power to breathe water is dropped in favor of a gills organ, while the player keeps everything else the origin offers.

The intended use is to load a world, pick an origin with the guide below, and play normally, with Chest Cavity's configuration file set so that KEEP CHEST CAVITY is true. Players who enjoy customizing their bodies can also use creative mode to add specific organs to the chest cavity by hand. Origins x Chest Cavity Compat requires Origins, and the environment is client and server, so the server and every player need the mod. Files target 1.20.1 only, the latest being 1.0.0, published on 2025-12-21 and released under All rights reserved.

Key features

  1. Conflict removal

    Origin powers that duplicate a Chest Cavity organ are removed, so the organ handles that function without overlap.

  2. Organ-based origin variants

    Several origins can swap their intestines, stomach, heart, appendix or ribs for Herbivore, Carnivore, Silk Gland, Insect or Small Animal parts.

  3. Blaze fireball ability

    The blaze origin gets a fireball ability instead of complete fire immunity, through blaze shells, a blaze core and functioning blaze rods.

Questions

Does Origins x Chest Cavity Compat need Origins?

Yes. Origins is the only required dependency, and the mod is meant to work with Origins and Chest Cavity together.

Yes. Installation covers the server and each player's game.

Which Chest Cavity setting should be enabled?

The author suggests setting KEEP CHEST CAVITY to true in the Chest Cavity configuration file, so the organs stay in place.

What the author says

First and foremost, this mod is not a fully automatic compatibility mod, rather a tool to mimic one. Instead of expressly replacing a player's chest cavity to mimic the origin; this mod merely removes certain origin powers that both conflict with an organ in the Chest Cavity mod, and can be easily mimicked by Chest…
