I Quote Absinthe; "Cinema slows down a lot, if you put several trees behind each other." Did you ever wonder why... I totally agree with XL that your conclusions about Cinema's speed are just absolutely foolish. Your "two trees and terrain" took more time to render than Carles Piles' "Daylight", #3 in Renderosity's C4D gallery. That imeage ( http://www.carlespiles.com/tut01en.htm ) took 5 min 45 sec... Makes one wonder what you're doing over there...
