Thought it might be useful to open up a topic specific to the X10's Physically Based Rendering(PBR) feature. Please share your experiences, tips and techniques.   Here's one I just ran based upon the Fire-Ice-Kitchen from CA's sample gallery.   Please note that the lights in this scene have been altered as have a number of the materials. Pleased with the result except for the fact that it does not render glass objects very well, there are two wine glasses in front of the wine bottle that did not show up, the island light has a glass component that did not show up and the glasses in the cupboard above the fridge did not render very well. Will play with the glass material settings to see if this can be corrected for.
