@Stonemason. That is simply amazing! I just read up on Z depth rendering. I understand instancing. As stated, I own the Utopian Blocks (I have almost everything you made for Poser. Purchase order or screenshot given upon request) and I also just joined the CG Society.

The background city lights that are seen behind the main city to the next collection of buildings in the background. Are those part of the Utopian Blocks and thus can be rendered with nightlights in DAZ Studio? Now that I know it was indeed postworked, I'm off to study Godray tuts for Photoshop 6.

Much thanks to the Master Builder, Stonemason. This humble thread has just become the Hall of Worthies.
