In vue i can render two image of all my render (even more but make it sample). One is my model without any shadow and the other is the shadow of my model alone. By putting the two together in combustion, AE or photoshop (shadow layer on top with multiply transfert) i can ajust the softness of my shadow and his opacity very quickly and without make a other long render. Is it possible in carrara or did a plugin can permit that? I saw a python script doing that for poser by exemple. Shadu
