If you are considering building for more than one platform, you may want to save SolarSystem as a prefab and then export it as a Unity package to reuse in a different project:
- In Hierarchy, select the SolarSystem object and drag it onto the project window's Assets/SolarSystem/Prefabs folder.
- Right-click on the SolarSystem folder and select Export Package....
- Uncheck Include Dependencies.
- Uncheck the PlanetMarkerHandler.cs script since it specifically has Vuforia dependencies.
- Export it.
Now if you create a new project or scene, such as for HoloLens or AR Toolkit, you can drag the entire SolarSystem prefab into that scene.
