First off i should say i am not a modeller, so null points i know about as much as carbuerator valves (nothing). But with regards to "How" they are adding the trade booms to the Tec Starbase?
I believe they are layering the starbase, in the same way they layer the planets, using callouts for each different mesh that is added for the overall image.
I could be wrong, and haven't verified this with any of the modders or the devs, but that is my guess from seeing how the planets are put together using multiple meshes.
Hope you get an answer and hope i havent steered you off course, take care,
