I'm currently trying to make a scene with "an island floating in the air"
Here you can see a drawing (a sketch) of this idea :

I have quickly made the island and the earth (just to test how to configure the igs file) :

The island is about 100-150 meters above the sea level.
Now I have a few question....
1°)
In this render, I have only put a "skyligth" with "extra atmospheric=false".
So there is a blue sky due to "extra atmospheric=false"
(and it's fast to render)
If I want to make it more "realistic", I suppose i must use an "atmospheric sphere"... I don't know how to configure this

What about rendering time ?
2°)
I really want to make nice clouds. I found a topic where Ono shows us very very nice clouds.... But it is not currenttly in the realease.
Any other solution ? If I must create them in 3DS, it will be a bit "difficult"

Thx and very sorry for my very bad english.
