The slides for our huge Lumen presentation in the Advances course at Siggraph 2022 are now up! We presented all of our work on real-time Global Illumination in UE5 to date, with lots of inside info from 'The Matrix Awakens' demo. #Lumen" target="_blank" rel="nofollow noopener">advances.realtimerendering.com/s2022/index.ht… @knarkowicz @_pmkelly

@Koola_UE5 Funny to randomly see my commits here

#ue5 Niiiiiiiiiiice

I'm finally writing up how Nanite Tessellation works. The first few blogs posts are up. More will be coming. graphicrants.blogspot.com/2026/02/nanite…

1 or 2 ?

@guycalledfrank I remember being so mesmerized by the road headlight reflections back then just like you posted =)

@EpicShaders Just remembered you even posted the code :) x.com/EpicShaders/st…

Caught these lovely asphalt specular reflections outside. Is there a game where they're actually this long? I only remember UE Samaritan demo with the funny hacked BRDF with stretched vertical dir. Doing it properly needs supersampling...

@bgolus @guycalledfrank I had to add MSAA support to the deferred renderer to get buy-in for it, even though it's a terrible tech matchup. No one wanted to give up MSAA to go deferred and we had no alternative at the time.

@guycalledfrank My favorite rendering feature listed for the Sumaritan demo: "Deferred rendering with MSAA support" The year afterward they turned on TAA.

My "No Graphics API" blog post is live! Please repost :) sebastianaaltonen.com/blog/no-graphi…

@EnDr_X @tillederdon @UnrealEngine You can get Height Fog on Lumen Reflections if you set r.Lumen.SampleFog 1, but not Volumetric Fog. VF uses some optimizations that only work for the primary view rays to be efficient, but we could do better than nothing.

@tillederdon @EpicShaders @UnrealEngine Hello Tilmann! Hope you are doing great man! Question for you. Is it still an issue on your side ? Cause on my side on UE5.6 I cant get Volumetric Fog in reflections. I’m I crazy or missing something ? What you see at the bottom, on my capture is a simple reflective plane

Soooo....lumen reflections dont see any kind of fog or am I missing something?😅 @EpicShaders @UnrealEngine

Check out this beautiful, fully customizable and interactive @CloviRenart's #Nanite grass for @UnrealEngine 5, now featuring subsurface scattering, increased density, enhanced wind, and more. Get it here: 80.lv/articles/get-t… #ue5 #unrealengine5 #environmentart

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: dev.epicgames.com/documentation/…

@rms80 Damn, sorry to see you go. I was always impressed by your work and your knowledge.

Today is my last day at Epic Games, please let me know if there is anything you’d like me to get done before I go.

Today on Digital Foundry, @oliemack takes a long overdue look at Teyon's exceptional RoboCop: Rogue City. Unreal Engine 5's high-end features are beautifully deployed to capture the original movie aesthetic - and it's excellent to play too. youtu.be/TYli86rF3X8

@JohnDraisey @knarkowicz Thanks! *slowly backs away from keyboard*

@EpicShaders @knarkowicz Hope you enjoy your break, stay away from the computer!

After 17 years at Epic Games and an intense few years launching Lumen in UE5 with @knarkowicz, I'm in need of a break, so I'm going on an extended leave. Lumen isn't done of course, and work on it will continue, just without me for the time being.

@raroni86 @knarkowicz @DanielMakeGames Thank you Rasmus. I won't be doing any indie dev, that would get in the way of taking a true break and being ready to return.

@EpicShaders @knarkowicz Absolutely well-deserved. Following your work over the years has been inspirational, thank you! Does this mean we'll hear more from @DanielMakeGames?

@SebLagarde @knarkowicz Thanks Sebastien, that means a lot.

@EpicShaders @knarkowicz Wow. You deserve it! Lumen and all your previous works have really contributed to push the industry. Thanks again for all your knowledge sharing. Have a great break.

#rtradvances from #SIGGRAPH2023 - presentation on Authoring Materials That Matters - Substrate in @UnrealEngine 5 from @SebHillaire and @kiwaiii is now online - enjoy! #Strata" target="_blank" rel="nofollow noopener">advances.realtimerendering.com/s2023/index.ht…

@MittringMartin At least they let you save it to Keep now, and you can download from there. But anything high resolution will be downsampled, so you still need to keep the original. I can only imagine the bureaucracy that must exist to prevent such an obvious function from being added.

I love Google docs. But why there is no have context menu "save image"? Any why do I have to fiddle with size manually to place two images next to each other.
