The first picture is a screenshot of my first scene in Godot and yes, a few things are missing: Normal maps and FXs for ship thrusters (waiting for Godot 3.0...hehe). I would add that I never found an easiest way to build a cubemap/skybox
A Blender rendering:
Rendered into Blender for the same reasons as above, indeed, to have a nice hologram FX, I have to use shaders, and Godot 3.0 will provide us a more modern system...if I'm not wrong of course.
Backup, comments, questions and especially advices are really welcome
