I make my "Renaissance 3D" visuals in 3D Modo and Octane. I keep post-production to a minimum; depending on the situation, I solve everything in 3D and let it render... When that's done, only a slight tweak in Lightroom or Photoshop make it perfect. Below: large and highly detailed "Renaissance 3d" photorealistic visuals.
