Hi,
I was working on a game tiles Scene / assets for a game.
For testing Evee and new features i downloaded Blender 2.8, without realizing that it made it self the standard Blender.
Next time i opened my game tiles file, it opened itself in Blender 2.8 and somehow overwrite the file.
If i open it in an older Blender version, the file is empty. If i try export it in Blender 2.8 to fbx, the file is empty as well.
Does anybody know a way, how i can recover the file ? Or do i just have to start over again ?
Thanks for your Help
