I have been reworking the shaders on a couple of mausoleums, exchanging the textures for PBR SuperFly rendering. The rendered image below has one 60% blackbody infinite light in addition to an ambient-light HDRI. The mausoleum on the right was completely reworked from its original build. I used the Group Editor to create new material zones and applied PBR textures downloaded from FreePBR. With the introduction of the RGB Colorramp node in the latest version of P13, I could apply the Cycles ambient occlusion node to the shaders of both models and improve the shadows in the render. As a note, I don't know if anyone noticed, but you can now see Cycles texturing in the Preview window.
