Here's a great video explaining/showing why the common CG practice of plugging smudge/fingerprints/dirt/whatever maps into roughness is wrong and why it should be done using material layering instead. This video is really well-made!

I've got a new blog post for all of you fine folks! It runs through the additions to D3D12 since it was released, and finishes up with some of the things that have changed for me personally in my code.
(And yes it's really been 10 years 👴).

Ten Years of D3D12
For those of us that have been using it from the start, it can be hard to believe that Direct3D 12 has been around for nearly ten years now. Windows 10 was released on July 29th 2015, and D3D12 has be...

Finally snapped: made a Vulkan layer that auto-labels objects with a stack trace at creation time. Now the validation layer can just tell me what I forgot to release on vkDestroyDevice :)

MegaLights slides were just posted online. There's a bunch of details in slide notes if you're curious how our new Stochastic Direct Lighting solution works, why we made it and want to learn a bit about the problem space.
#SIGGRAPH2025 Advances in Real-Time Rendering in Games course slides for "MegaLights: Stochastic Direct Lighting in Unreal Engine 5” talk by @knarkowicz.bsky.social and @tiagocostav.bsky.social from Epic Games are now online

I like tonemapping because you read a few thousand words of text and then basically copy-paste a single short function and move on with your life.
