Xcode plugins can now extend Reality Composer Pro 3 by registering custom ECS components, systems, animation actions, and Script Graph nodes so artists can iterate on 3D content directly inside the editor without rebuilding the app.
ā¢ Artists and designers can tweak custom component properties (like water level or vortex speed) in real time inside the editor, dramatically reducing iteration cycles
