The procedural data for every system and planetary body is already in game, it is not made up on the fly.
Do you have a source for that because given that commanders have only explored < 1% of the galaxy it would make a lot of sense to only store what they needed to.. Cloud storage costs money and it'd make sense to only generate topographies for all those planets (presumably the largest thing to store) if someone actually visited..

They use COBRA their in house engine.
Sure, but COBRA will be written in a language.. Probably C/C++ since it's been around a while... and I get the impression FDev are old skool.
