Final Frontier - Updated
Realtime Cubemap Camera?
It seems to me this borrows certain aspects of Elite.
These 2 ships are stationary rooms that have some sort of camera they control around a skyzone.
How do they get this to work in Source?

I want to better understand how to replicate this effect If I want to make the Treasure Planet version.
Is it possible to have more degrees of freedom with maneuvering this camera?

Its seems the Final Frontier map is 2 axis
