Thanks erbsen, for black sprite is exactly what I want.

for rotate cloud2, Rot param only affect y axe. I want to rotate z axe to simulate falling particles to simulate snow or rain for example.
I've checked code and it's easy to add rot param for x and z, but I want to know ifthere is a trick to do without modification.

:)

hi, ikam
imho 2 options available:
1) you can place yellow Transform op (tweak Rotation param) after Sprites op, but this will affect all the clouds at once...
2) use Wobble modifier op after Clouds2 and tweak it until you are happy. Chaotic stuff, but it may work. ;)

PS I like the idea of adding x and z rotation axises to Cloud2 through code modification. I would be glad if you could add it to the trunk!

Ok, black particles are done.
I did snow without Cloud, maybe it's what you want.

Thanks erbsen, your example is nice.

Cloud2 with new Rot param is very cool, I'll post a patch.
