QuestCraft uses the Fabric mod loader — the same loader used by desktop Minecraft: Java Edition — to power its modding system. Mods are placed in QuestCraft’s mods folder and are automatically discovered and loaded by Fabric each time the game launches, giving you a familiar and flexible modding experience directly on your standalone VR headset.

​
How Mods Work

When QuestCraft launches, Fabric scans the mods folder inside your QuestCraft data directory and loads every .jar file it finds there. Each mod runs its initialization code before the game’s main menu appears, which is why mod-related errors typically show up early in the loading process. Because everything runs on Android hardware rather than a desktop PC, performance-focused mods are especially important for a smooth VR experience.

​
Mod Compatibility

For a mod to work with QuestCraft, it must meet two requirements:
  • Fabric-compatible — the mod must be built for the Fabric mod loader, not Forge, NeoForge, or another loader.
  • Correct Minecraft version — the mod must target the same Minecraft version you have active in the QuestCraft launcher. Mods built for 1.20.1 will not load correctly in a 1.21.4 instance.
Not all Fabric mods are compatible with QuestCraft. Some mods make assumptions about desktop hardware or OpenGL features that are not available on Android. Incompatible mods will cause crashes at launch. If the game fails to start after installing a mod, that mod is almost certainly the cause. Additionally, Vivecraft and Fabric API are required core components and cannot be disabled — any mod that conflicts with either of these will not work.

​
Installing Mods

There are two ways to install mods on QuestCraft: The QuestCraft launcher includes a built-in Mod Manager that lets you browse, download, and install mods, modpacks, and resource packs entirely in-headset — no PC required. This is the recommended approach for most users because it handles version filtering and file placement automatically.

2. Manual Installation

Advanced users can install mods manually using a file manager app. Place .jar mod files in the following directory on your headset’s storage: 
Android/data/com.qcxr.qcxr/files/games/instances/<instance-name>/mods/
Make sure the .jar file is Fabric-compatible and matches your active Minecraft version before copying it over.

Pre-installed Mods

QuestCraft ships with a curated set of mods already enabled to ensure the best out-of-the-box experience on standalone VR hardware.
All pre-installed mods can be toggled off and on when creating a new instance — except Vivecraft and Fabric API, which are required core components and must remain enabled at all times.
