What i do is to make a volume container for the lightrays, assign a transmat in the mental ray shader-override for material and shadow, then add a Parti_volume node for the scattering. So far, so good, after some tweeking and adding a physical light node into a maya lght I get a pretty decent image like the attachment (ignore the wierd shadows). The PROBLEM is, that if i want to get smooth results, i need a pretty BIG container... and i CAN NOT enter with the renderable camera into the volume container. It just doesnt render the light... I have tried adding another light with photon emission into the container, than adding a photon_parti_node into his photon-volume attribute... but still doesnt work. I will be very glad, if there is some experienced mental ray artist (or just anyone who knows what I am talking about
), who can help me solve this problem,. Thank you!
