UPDATE: Fixed links to images below (hopefully). Also trying to get glossy reflection and refraction working together in one shader.
Been re-working this glossy shader for better speed, but still running into bugs. Thought I'd post a comparison render (straight mirror vs. glossy/brushed look). Brushed metal render was 5 minutes on a 2GHz Intel i7 laptop with 6GB of RAM.
My original shader used an array to hold the blur offset values, but the new shader uses a loop to keep averaging samples together. The original shader used straight random numbers to blur things, but I'm trying a hybrid random+noise function. It can also self-reflect quite well. I hope to post a working, usable shader soon.
