Overview Welcome to the Chillin Bros Pack — a laid-back, optimized Fabric modpack for Minecraft 1.20.1, carefully curated for players who want a richer experience without sacrificing performance or simplicity. Whether you’re building, exploring, or just hanging out with friends, this pack gives you a smooth, enjoyable gameplay experience with a few magical and decorative mods added in for extra flavor.
Why Play This Pack?

-
Multiplayer-ready: Great for playing on a server with friends or hosting a friendly, relaxed survival world.
-
Magical touches + QoL: Enhancements to exploration, world generation, and usability, plus a few magic or utility mods to make life more interesting.

Installation Notes
-
Fabric Loader Required: This pack requires Fabric loader ≥ 0.17.3.
- Java Version: This modpack requires Java 21 to run correctly. Some launchers may default to Java 17 on first launch, which will cause errors. If this happens, simply switch the instance to Java 21 using your launcher’s Java settings. (Step-by-step instructions are included in the gallery.)
-
Memory: While lightweight, we recommend allocating at least 4–6 GB of RAM for a smooth experience, especially in multiplayer or heavy building sessions.

Known Issues / Caveats
-
Some mods may require you to tweak your Java launcher settings or instance configuration (especially if your launcher defaults to older Java versions).
-
Random chunks not loading during world generation, causing surrounding chunks to be invisible. Currently exploring reasons for cause. Tempoarary fix to fill failed chunk with solid block.
-
Controlify (controller support mod) conflicting with mod config screens, causing crash. Current workaround to disable controlify when editing mod settings, then re-enabling once happy with changes.
Future Plans
-
Occasional updates to keep mods up to date and compatible.
-
Possibly adding optional modules / packs (via overrides) for more magical or decorative content without bloating the core experience.
-
Community-driven improvements: feedback is welcome — if you have ideas for QoL, decor, or light content mods, I’m open to adding more.
