  3. Save project and scene.
  4. Build project and run.

Wait… there’s something wrong with these steps.

if you create a plane, save PROJECT, then close and open up unity again, and then try to create a plane again it will come with the gray default. If you want to save it, you need to save the SCENE, or make a prefab of it.
