Loving the game so far. Space Trucking Inc. rules. Do hope they'll add more content as time goes by. Missions, player interaction, events and, especially, sights and shit to discover. More station designs would go quite a way already. Not even speaking about asteroid bases and the like.*
Anyway, that lovely icing effect. What is it tied to? Silent running with all the systems shut down for good measure doesn't do it. Play the game at high settings, so perhaps it's tied to that?
*Fuel stations in the upper stellar atmosphere of a star, ancient floating derelicts, mining stations in the oort belt, bizarre alien scultpures, a ringworld. Really, there are decades of sf to take inspiration from. Put some awesome shit to find in that void.
