A promo image for www.vfxtour.com Rendered in V-Ray. I leave for the country Colombia in the morning to present the entire workflow with the 4 other artists involved. We have about 6 shots to present in HD with a full ptex lighting workflow that includes plate photography all done with Ptex. Showing workflow from concept to final picture.
