  1. Thank you so very much, What happens when it is an interior but in the night with lamps? The solution to that is on the Sample settings on the Clamp options if you had added an Indirect map, then add 0.5 to the indirect clamp, and noise is reduced, and fireflies disappear without compsotting nodes. My question is: If I add that trick on the night interior scene,it will reduce the noise?

  2. Great, but I have tried using portals many many times and all my attempts failed >>> the render takes longer time, and the result is more noisy when I am using portals, which doesn't make sense!!
    I don't know which step I am missing ..
    I downloaded Andrew's file, and the portals seems to work fine in it. However, when I want to reproduce the effect I am always failing ..

  3. Ok, I don't do these graphical things myself, but yet I find myself watching the videos. :p

    Great stuff!

    Is there any reason not to have the portal lamps implemented as a standard when doing these renderings? Are there any side effects?
