A WWDC26 session walkthrough on extending Reality Composer Pro 3 with custom Xcode plug-ins. Covers building custom RealityKit components and systems that run live inside the editor, allowing artists to tweak properties in real time without rebuilding the app. Also demonstrates adding custom animation actions to the sequencer timeline and exposing custom nodes to the Script Graph visual scripting system using the @Scriptable macro. The workflow involves a shared git repo between an Xcode project and a Reality Composer Pro project, with a plugin framework bridging the two.
