Hi people, this is a fast, with a very tight schedule visualization we do for a New York client these days.
Created with 3DS max and Vray; Post production with Photoshop.
Vray sun + HDRI
Pre calculation Irradiance map + Light cache (75% smaller than the final resolution) = 30-40 minutes
Final render 5000×2500 Pixels = 1:40 minutes
(The follow image is a full resolution 5000×2500 pixels, may take e little more to load!)
