Prefabs

Prefab patches let mods change Unity prefabs without distributing replacement copies. Several mods can patch the same stock prefab: Patch Manager resolves their requirements and order, applies their operations to one effective prefab, and reports conflicts or invalid targets.

Guides

• Getting started explains the model and walks through a first visual patch from linked stock prefab to packaged manifest.

• Visual authoring covers supported prefab overrides, stable IDs, references, dependencies, and ordering.

• Code authoring covers the C# and Lua frontends.

• Compatibility and troubleshooting explains preview, diagnostics, pm_summary.log, and common failure modes.

The normal workflow

1. Create a linked Addressable for the stock prefab.

2. Create a prefab-patch variant from that link.

3. Edit the variant in Unity and save it.

4. Preview the effective prefab.

5. Build and deploy the mod normally.

6. Open a campaign that has your mod on. Test the content that instantiates the prefab, and examine pm_summary.log.
