Original version with post-processing

New version without post-processing and after ambient lighting overhaul.

As you can see, general tone of ambient lighting is dark. Which fits mood and setting of the campaign as well as brings some flavor of realism into play. In WiH missions you will see that amount of ambient lighting will vary depend on how far away from the Sun mission is taking place. Battle in above screenshot is taking place near Europa, quite far away from the Sun.
Post-processing has been moved to experimental in 3.6.12 RC2 due to buggy implementation causing memory leaks and other issues that may cause crashes.
