Creating a Project in Lumion - Mastering Lumion 3D - page 26

The Files button is represented by a floppy disk icon and when we click on this button,
the tab that is open is precisely the Save scene tab and as you can see in the following
screenshot, there are a few things that we need to fill before saving the scene:
Firstly, we need to give a name to our scene, which is something pretty obvious to
do. We fill the Name box and if you wish to add a small description to the scene, you
can do that on the Description box. Adding a description may prove valuable, in
particular, if we are saving several versions of the scene. Then, you may enquire why
the screenshot in this page is different from what you have on your screen.
How the save system works
The reason why the previous screenshot is slightly different from what you have
is because the scene was already saved and in this particular case, five times. The
first time we save the scene, Lumion creates a version 0 and every time the scene
is saved after that, Lumion increments the version number. Great, we may say,
because if something goes wrong, we can open an older version and start from there.
Unfortunately, this is not the way Lumion works, so don't let this version number
deceive you to think that somewhere we have the previous version saved because in
reality, when we save the scene a second time, we are in truth overwriting the scene.
