Greetings everyone. My thread is adressed to Epic devs mainly. In fact Mr Ivey told me to make a thread about it so devs will look into it. Many of you surely know Jorge Jimenez: the creator of SMAA and SSSSS (Screen Space SubSurface Scattering) which was included in 4.5 update. Well genius never stops his advancements and created with other geniuses a better version of SSS (Screen-Space being the least perfect in approximations) and called it Separable SubSurface Scattering. Here is his tech explained in those two videos:
Research papers are available here at Károly Zsolnai’s page : Separable Subsurface Scattering – Computer Graphics Forum 2015 (presented at EGSR 2015) – J. Jimenez, K. Zsolnai, A. Jarabo, C. Freude, T. Auzinger, X-C. Wu, J. von der Pahlen, M. Wimmer and D. Gutierrez – Károly Zsolnai-Fehér – Research Scientist
I hope Epic staff take note about it and try to contact him and get it in UE4.
Edit : Oh what? The explanatory video has been put to private. It explains everything about the new tech. In his site it says: "Talk (unofficial) – temporarily disabled, it may be back soon!
UPDATE: Separable SSS is officially released now
Source code available on GitHub: GitHub - iryoku/separable-sss: Separable Subsurface Scattering is a technique that allows to efficiently perform subsurface scattering calculations in screen space in just two passes.
