Exporting scenes
Saving a scene by using Ctrl+S or one of the "Save ..." options in the main menu will save
the scene in a format that can be opened again by the editor, and used to continue editing
the scene. This is not the format that you should use to load the scene into your game.
To make a file that you can load into your game, you should use the 'Export' -> 'Save raw info'
option from under 'File' in the main menu. You can read more about the differences between these
two formats in the difference between saving and exporting topic.
Export options
For each scene you can set various options for what items to export, and how to treat paths
for images. See the Export options topic for more details.
