I have been reading arround but i want expert people to please answer me.

But if i have read ok, people say that skydomes are slow for the games and the skycubes are better in all ways.
Are there any tutorials for making skies and programming them in GameStudio?
Is there any tutorial for making skies?
IS there any tutorial for dynamic skies with clouds moving and sun? (or a demo to see how does it look)

Thx.
