KSP Unity Internals

[bizzehdee]

I have been wondering, out of curiosity, how is KSP broken up into different scenes within unity?

I get that the KSC overview, the menu, settings VAB are all seperate scenes, but... From the launch pad, is the whole kerbal solar system 1 large single scene with a LOD system on top of it? Or do we have seemless scene transitions between the surface of individual bodies, and then space being its own scene?

Again, its a curiosity, would be interesting to know how it works and how its managed.
