For modders

Use loader files to connect supported game data, or bring your own cooked assets in a PAK. RuneSchema is a runtime bridge, not a button that cooks Unreal assets for you.

Make your first modStart with a small loader file. Add a cooked itemMount, resolve, register, then test. Choose a loaderFind the folder and fields for a feature. Browse examplesCompare working layouts and definitions.

Follow the content chain

For a cooked feature, check each stage separately: the PAK contains its dependencies, RuneSchema mounts it, the object path resolves, any required native registry accepts it, and the feature works in-game. A successful mount does not establish the later stages.

Start with the guide closest to what you are making:

• Items, ranged attacks, and magic
• Stations and recipes
• Custom armor
• Cooked registry declarations
• Blueprint and Lua companions
• Guided in-game authoring tools

Before publishing, test a new character and a backed-up existing character. Check first world entry, re-entry, a full restart, and the server/client combinations your mod claims to support.
