help me to model a sky in both internal and cycles!

help me to model a sky, a little cloudy, in both internal and cycles PLease! I dont want to use sky stocks in my work, so I must learn myself.
Help please.

There you go for blender internal. Cycles is a bit trickier since it doesn’t have volumetrics at the moment.

Thank you for the links, but i need to learn in cycles too, as internal is pretty tough according to me and I also can’t produce a high quality image in internal :stuck_out_tongue:
