I've already have a sky, a dodger blue sky (nice day huh? )
I generated this by device.clear (not a good solution, i think)
So if I want to make a sky, i'll create a mesh, move it upwards my head with some cloud texture, or just clear the device and place on some clouds?
More: If there's a "Sky" mesh, so i must do it like a roof, doesn't it?
