There are no doubt than C4D is hundred times faster (!) than Vue, of course !!! This soft is famous for this particular feature, some tests have been done before by Audity which is now the C4D forum moderator...I'm myself a new C4D user (and still a Vue user). You must compare the same thing, particularly in terms of lights. Absinthe's Vue picture has no soft shadows, and his C4D picture has soft shadows ;=) The difference is here. I can confirm than C4D never render in more than 1h with the best settings for 640x480, as for the same pic in Vue it could not be done in hundred hours ! Even for a single sphere ! And the result is much better in C4D, sorry to say that here... Vue Rendering engine has not be changed between "Pro" or not "Pro" The interest for Vue is not in rendering fast, it is in "easy use" especially for "landscapes" pictures. IMHO, Yves
