I would have said I first and last used the NMS Base Building app maybe a year ago but according to the saved scene files that was actually almost 2 years ago. I built a Vy’Keen Amphitheatre and a Gek First Spawn Conversion Centre for Korvax for a themed build system
Since cross plays release I’ve been meaning to tinker with bringing a console base over to PC and adding some details I would only find painful to pull off via normal or glitch building methods.
I guess I never returned to it because of the stop start nature of hybrid building and losing that creative flow in the breaks while transferring from app, back to save editor, and into game loading screen for testing, in-game additions and re-exporting, ad nauseum.
But the hybrid approach of “build a little in game, go crazy in app, bring back to game to check and test” is worth it because I would never have the patience to do something like this without it.
Building a rickety bridge for a certain something 
The tiles/hanging lights were placed in game so I have an idea of the grounds layout in the app.
If anyone has a PC and experience with any 3d software (even poser or 3dsmax) I do highly recommend trying out base building with the standalone app or blender plug in (if you are familiar with the software I hear it’s fantastic). Even if you have no experience with 3d software it’s quick to learn and has some useful guides.
