Can you send a screenshot of what prefabs are missing? I was able to get similar issues with the Pong example scene, however these are only warnings and don’t stop build on my side. Any of the prefabs used in Lightship will come with the ARDK, so it should just be a matter of finding them if they aren’t linked in the new project. Prefabs will have a blue appearance and can be added to empty fields in the inspector by clicking on the bullseye style icon on the right of the object field.
