Subject: [IML] QUEST: Construction of Clouds
Hi together
Has anyone experience in construction of clouds with IMAGINE? I will let
flight a spaceship around, and fly throug the cloud to make a kind of approach
to a space-center.
I've tried to build clouds with Metaballs but the result looks very
unrealistic.
Any help will be very appreciate.

Maybe you should try diffrent layers of planes with the cloud texture on em'
and apply diffrent filter settings, so that the lowest one has the highest
filter
settings.
But, the cloud texture is really painful to render in an animation(eg for me
with a a1200/030/50/50/882..)

I haven't actually tried this but it should work. He was right when he
said about the layers of clouds, but don't just make them layers, make
them cross each other. So you would have about 5 or 6 of them at an
angle, then when your plane or whatever flies through them, you
wouldnt see them as flat.
