New blog post: A Decade of Slug This talks about the evolution of the Slug font rendering algorithm, and it includes an exciting announcement: The patent has been dedicated to the public domain. terathon.com/blog/decade-sl…

Real-time Rendering with a Neural Irradiance Volume arnocoomans.be/eg2026/

Excited to share that GPU Zen 4: Advanced Rendering Techniques is officially out. This volume features work from some of the most visually impactful projects of recent years, including #AssassinsCreed , #DOOM , #StarwarsOutLaws and NVidia's Zorah. And a killer cover :)

@colour_science RGB Colour Spaces: ACES family, ARRI, RED, Leica, Fujifilm, Sony, Canon, Panasonic, Fujifilm, Nikon, DJI, GoPro, sRGB, Rec.709, Rec.2020, Display P3, DCI-P3, Adobe RGB, ProPhoto... 100+ spaces total. 2/15

Found and solved a years-old bug in Unity's HDRP IBL system. Turns out using the same sequence for every pixel + a local basis with a singularity leads to visible seams on rough metallic surfaces (who would have thought?). auzaiffe.wordpress.com/2026/01/10/sam…

After nine years of development, meshoptimizer has reached its first major version, 1.0! This release focuses on improvements in clusterization and simplification as well as stabilization. Release announcement with more details on past, present and future is below; please RT!

My third and final blog post on spectral rendering is out. This one compares results of RGB and spectral rendering under different illuminants and draws conclusions. momentsingraphics.de/SpectralRender…

Do you want to improve the performance of your il2cpp Unity projects, without changing your code or your assets? My il2cpp build processor cpp2better is now officially available (on request). Reach out to me, details here: blog.s-schoener.com/2025-11-04-cpp…

I am pleased to share a small but valuable Unity feature I have been working on recently. It enables customization of certain visuals for each renderer at no additional CPU performance cost. discussions.unity.com/t/renderer-sha…

@SebAaltonen True. Sadly it is harder to get survey/feedback outside of your own engine communauty. Outsiders giving them may be another bias :). What would be nice is to have access to others survey/feedbacks. Guess the apprpach here is to read public forum of other engines.

It's completely fine to focus on a subset of customers, but it's super important to realize that surveys targeting your own customer base don't give you good information about the potential of growth related to adding missing features or improving performance.

Survivorship bias is important in engine development. If you are lacking critical features, you already lost customers requiring those. When you do a survey for your customer base, asking what they need, they don't list those missing things. Devs needing those use other engines.

Will be talking about idTech 8 Global Illumination at CEDEC 2025. Visiting Tokyo/Japan for first time - very excited. cedec.cesa.or.jp/2025/timetable…

Have a few last-minute things to wrap up, looking forward to dropping this tomorrow morning :) #unrealengine #ue5 #gamedev @unrealengine

@Auzaiffe Congrats man! Well amount of research/publication/blog you have done at Intel with ggx's team. Good luck for the next step

Last week at #Intel! Grateful for the chance to work on cool research in rendering + ML, with real impact on the GPU product line. Big thanks to everyone I got to learn from and work with, it’s been a pleasure. On to the next adventure! 🤖

The papers session on Rendering is now available! youtu.be/Jj80CZ_1sMY #I3D2025
