Just got this idea about a really local weather system produced inside a glass jar... Being in a temporary "production mode", I tried to make it as fast as possible while maintaining a good quality - and ended up with a total of around 14 hours work (not including rendering of course).
Aside from standard C4D features, I've used PyroCluster for the smoke/cloud. The grass is generated polygons, around 220 K, and it's been rather heavily post processed to give a fluffy, toyish look.
Looking for overall crits and comments.
