My erosion filter is out! Video, blog post, and shader source. It emulates erosion without simulation, so it's fast, GPU friendly, and trivial to generate in chunks. Explainer video: youtube.com/watch?v=r4V21_uU… Companion blog post: blog.runevision.com/2026/03/… #ProcGen #vfx #GameDev

In the coming days, employers will see a stream of resumes of once-in-a-lifetime quality folks. An important thing to understand is that Epic never lowered our hiring standards as we grew, and the layoff wasn't a performance-based "rightsizing" as companies call it nowadays. It's a sound bet that anyone with Epic Games on their resume is in the top few percent of their discipline.

What's this? Info on Unreal's next-generation terrain solution? 👀 Full 3D, enabling overhangs and tunnels?! Multi-user non-destructive modifiers, and it can still import heightfields?! Both Nanite and trad LODs 🤯dev.epicgames.com/community/…

Slug algorithm is now open source and patent is public domain! Thanks Eric! Hopefully this means that awful font rendering in some apps and games will be a thing in the past.

So I discovered an interesting technique for refraction/distortions by putting the iterator step into the turbulence wave function (so each iteration has slightly different turbulence)

If you’re ever staring at a progress bar in PIX and wondering what’s going on, there’s a log output in File > Output that usually has details.

I wanted to do a side-by-side comparison of my procedural animation to hand-authored animations on some models I bought. This is so I can better study what I need to improve. When I got my comparison tool running for the first time, this is what I was greeted with! 😅 #ProcGen
