Loopable video (1280x1280px, H.264, 30sec@60fps). This is my second attempt in researching photorealistic PBR Materials and depth of field in a real time rendering environment, using HDRI environmental lighting. The challenge was trying to find some kind of refraction shading. Unfortunately I did not find a perfect solution yet, but I will keep on digging :) [This work is released under Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0) License]
