What Does This Mod Do?
If you have spent more than a few nights in Minecraft, you know the problem: zombie flesh piles up in chests with no real purpose. Feeding it to wolves gets old fast, and on hardcore servers, it is just dead weight. What Does This Mod Do? solves this by giving rotten flesh a second life as leather. It is a focused, no-nonsense utility that fits neatly into any survival workflow.
Core Functionality
Leather is always in demand for books, item frames, armor, and countless modded recipes. Traditional farming requires cows or rabbits, which is not always practical early on. This mod introduces a conversion mechanic that turns excess rotten flesh into usable leather. The author openly notes the idea is adapted from earlier work, refined for modern game versions. The result is a balanced alternative that does not break progression.
Four Editions: Pick Your Grind
The standout feature of What Does This Mod Do? is the choice between four distinct crafting paths. Each edition is color-coded and offers a different approach to conversion. You select the one that matches your playstyle.
Red Edition
This is the most involved route. Nine rotten flesh craft into flesh pieces, and nine flesh pieces combine into one leather. That is 81 units of rotten flesh per leather. It is a heavy grind, but it fully justifies the "advanced" in the mod name. Ideal for players who enjoy multi-step production chains and want a sense of accomplishment.
Orange Edition
For a quicker result, the Orange edition crafts leather directly from rotten flesh with sugar and bone meal. Sugar comes from cane, bone meal from skeletons, so ingredients are easy to source. This is the go-to option for survival play where speed matters more than realism.
Blue Edition
This version introduces smelting. Simply cook rotten flesh in a furnace to get leather, just like ore into ingots. No extra components, only fuel and time. It works on Minecraft 1.13.2 and newer. The most intuitive method: drop it in, wait, collect.
Blue Plus Edition
Available from 1.14, Blue Plus expands smelting options. You can use a furnace, a smoker, or a campfire. The smoker processes faster, while the campfire adds a traveling vibe. If you are always on the move, this edition fits seamlessly into your routine.
Installation and Version Compatibility
What Does This Mod Do? supports both Forge and Fabric loaders. For Fabric, you must install the Fabric API; without it, the game will not load the mod. On a server, place the API in the server mods folder as well, or clients cannot connect. The mod covers a wide range of versions: Forge from 1.12.X to 1.16.X, including the combined Rotten Flesh to Leather X 1.6.5 for 1.16, and Fabric from 1.14.X to 1.16.X. A 1.17 snapshot version was announced, keeping it relevant for upcoming updates.
For those who prefer a streamlined setup, the foxygame.net launcher offers a mod catalog directly in its menu. Find What Does This Mod Do? for Minecraft, click install, and the launcher handles version matching and dependencies automatically. This is especially useful when juggling multiple modpacks across different game versions.
Integration and Extra Features
The mod does not conflict with popular modpacks and even provides its own item, flesh pieces, for third-party recipes. If you use CraftTweaker or KubeJS, you can reference these pieces in custom crafts. The author mentions the Advanced Bow System mod as an example that uses flesh pieces. A ready-made example for Fabric and Forge 1.14.4 is available to get you started.
Final Verdict
What Does This Mod Do? is a small but thoughtful addition that addresses a long-standing player need. It does not overload the game or introduce unnecessary entities. Instead, it offers a fair choice: pick Red for realism, Orange or Blue for speed, or Blue Plus for a background process that never interrupts your flow. If your chests are full of rotten flesh, this mod gives it real value. Select the edition for your version, and enjoy a new leather source without touching game balance. To get started, download What Does This Mod Do? and follow the simple install steps for your loader.
