Hello
I am developing a rpg game
Sky is not strictly necessary
The compiling time for my map with and without the sky box is substantially different (with a factor k = 10)
FPS is about the same
Light and shadow effects are also different even though position and direction of the sun are the same
Better with sky box , in my opinion
The question is
Is the sky box alwayes needed ?
Common sense would say
Add a sky box, just in case the sky is visible in your game , but apparently both the manual and comparative test , disagree
