Thanks for the comments so far guys. The vent/Hud and Splash-back shader I modified many times, but I found it hard to get the correct amount for the brushed staneless steel look as it wasn’t until the final few samples that it was smooth enough to tell. The Lights over the Radio and work surfaces come from under unit lighting, which as they are lower wattage in real life have a slight orange/yellow look. Probably because the mesh emitters are quite small, the shadows from them are probably quite tight and darker in contrast.
Ballancing Light is pretty hard in Cycles, especially when the smaller the light source can produce bad anti-alaising if set too high and change the ambience.
As I mentioned in the PDF included, it’s not meant to be photorealistic, just an approximation to get as near as possible with reasonable render times for Archviz. I was hoping that some blender newbie would learn something from it, and maybe eventually improve on it eventually, plus these complete scenes are good for testing out render times and render engines.
I really look forward to see what others might come up with for Archviz in Cycles - and hopefully better me by a mile, so I can disect their blends!
Jay.
