Hi Tom, Thanks for your post, they indeed make the sim look more beautiful. I quite like the lights tweak too (by the way what would you recommend doing to make the lights brighter at dusk/daytime too?) Let me contribute by adding a third file to improve water (I found it on another forum, I'm just reposting it) just save it as water.lua set( "sim/private/controls/water/deep1_b", 0.710000 )set( "sim/private/controls/water/deep1_g", 1.040000 )set( "sim/private/controls/water/deep1_r", 0.020000 )set( "sim/private/controls/water/deep2_b", 0.950000 )set( "sim/private/controls/water/deep2_g", 0.113000 )set( "sim/private/controls/water/deep2_r", 0.190000 )One more thing, your tweaks look great at relative low altitudes but the give an unrealistic cyan tint at 10-20k feet, have you considered putting down a few if statements and switch colors base on height?
