Poking into the needed effort to get exported projects of #Unigine 2.16 & #Godot 4.0 seamlessly integrated into Linux desktops.
The examples are hardly more than default scenes. In the case of the Godot project, I just quickly imported some random assets from #SketchFab... otherwise the default scene would have been empty.
Unigine and Godot are much leaner than Unreal Engine. They still allow me to use their project-editors on a 4-year-old ultrabook. Unreal only works comfortably on big iron.
