In my experience 1024 x 1024 is enough,.....if I double that to 2048 x 2048, I see no visible difference
in game,.....maybe later it may make a difference, but for now 1024 x 1024 is fine.
As for Rolfy's fantasy skybox,.......it is supposed to be that way, because it's "fantasy", but I'm sure
he will make a more "realistic" forest skybox soon.
