yes that's a bit mean, but as I already asked, I wonder why he didn't try to render these clouds by himself...
I mean, TG2 has a very good free version and everybody is very welcomed to use it and ask for info and tips from everyone.
A lot of people already did a lot of clouds renders and they often post the render time too, so I was very surprised to see somebody not asking for average render time of this kind of render (the search tag is not very easy for some people, as in every forums) but ask for people to render some stuff and post render time...
anyway, I hope the guy didn't take our jokes too seriously and will come back to give some details about what he wants and why he doesn't try to do it by himself
