second imagen really looks nice, glad u post this images here, bcuz i never read vray forums
PD: I don´t use mentalray for animation and to be honest im afraid to use it , right now im doing a personal project based on a scene from kickass(the movie) and im gonna try to make a video, and i didn´t want to sound mean with my comment, but there is a lot of Vray experts that only read Vray forums so maybe you can get more info there.
Have a great day
