Is it possible to save (or export) the current scene to file and reload it into Unity later?
For example, add some cube, lighting, etc in runtime, save that details to a file and then import that to reconstruct the scene.
Also can anyone please show some tutorials how the game-like environment for architectural modeling is done as in the link below, http://www.youtube.com/watch?v=Uqe6QQ-nuuw
Go to Assets → Export Package…
Then you will be shown all the dependencies. Select the necessary assets to export and a custom unity package will be created. Import the package in other project to re-use it.
