Getting started
Start here if you have not authored a prefab patch before. These pages take you from the basic model to a compiled, packaged visual patch.
What prefab patches are explains when prefab patching is the right tool, how it differs from replacing a prefab, and which authoring workflow to choose.
Create your first visual prefab patch walks through linking a stock prefab, creating a variant, making an Inspector change, and compiling it.
Test and package a prefab patch covers previewing, in-game verification, Addressables ownership, and what belongs in a release.
Read these in order for your first patch. Once it works, continue with Visual authoring for added objects, references, and cross-mod coordination.
