    Together with @EpicShaders and @_pmkelly we are doing an in-depth talk on Lumen at #rtadvances. We'll cover (virtually) how we trace rays, reuse computations, solve the whole indirect lighting path and noise, and scaled all of this to "The Matrix Awakens". advances.realtimerendering.com/s2022/index.ht…

    Lumen took a lot of exploration to reach shippable state. This ability to focus on a single thing is an awesome perk of working at Epic and I wanted to shed some light on early techniques I worked on with @EpicShaders and which we later discarded:

    Finally, it is public! So happy to have a chance to work on the Lumen (real-time GI) for the UE5!

    MegaLights release took me a bit by surprise. It was just a small prototype on a backburner, not planned to be showcased in UE 5.5. Now trying to catch up after the demo push, starting from writing the official docs which just went online:

    After seeing some crazy C++ code I'm thinking about giving tricky template questions to candidates and do ​*not* hire if they can solve them

    Lumen went through many changes and challenges, with more ahead of us. Already UE5-main has features which didn't make it to Early Access :). Today we can pause for a while, and be blow away by the amazing things community is doing on the 1st day of UE5 EA

    I'm just testing #UE5 with Nanite and Lumen for some virtual production demos. Have no words. Nothing will be like before. #NFTs #CGI #UnrealEngine5

    SIGGRAPH ReSTIR course materials are amazing. They also just uploaded Cyberpunk Overdrive slides. Indirect/emissive/skylight is handled by "naive" BRDF sampling. Analytical lights use MIS to mix ReSTIR and "naive" BRDF sampling (reused indirect rays). intro-to-restir.cwyman.org

    Epic's fall rendering internship position is an unique opportunity to be a part of Epic, when we are building our next gen UE5 tech. Don't be discouraged by Cary/Larkspur. It's a remote position and I'd love to see more people applying outside of US! epicgames.wd5.myworkdayjobs.com/en-US/EpicInte…
