Unreal Scoop: Make your own “shaded textured unlit” viewmode real quick

Hammer, king of level editors, has a view mode where the scene is unlit, but not fullbright; it’s shaded to make it easier to parse. Unreal doesn’t have that! But you can add it yourself, really easily, with no C++ or Blueprint – just a postprocess material and a line in a config file. Here’s how!

Mesh Outlines Without Post-Processing in Unreal Engine

Some time ago I saw a neat solution by Cory Spooner on outlining meshes using particle sprites. The concept has been done before – but it’s interesting enough to cover it regardless for Unreal Engine...

Unreal Scoop: Making a “Compiling Shaders…” Screen

Unreal has a reputation amoung the ill-informed for being plagued by shader compilation stutter. As an attribute of Unreal itself, this is basically made up – devs are just not always doing what they are supposed to do pre-ship to avoid this issue. I’ll elaborate, but basically, to avoid compiling shaders during gameplay, you want to do it up-front, like during an initial loading screen, which maybe says “Compiling shaders” on it, and not let the player begin until it’s done. To do that last part properly, you need a little bit of C++. I had to do this for InFlux Redux recently, so here’s mine.

Understanding The Math Behind ReSTIR GI

Recently, I had the pleasure of contributing to Nvidia’s Zorah project, the flagship demo for the RTX 50 Series GPUs. My primary role was to provide technical support for light transport in Zorah, which included collaborating with my colleague Daqi Lin to implement a brand new ReSTIR-based global illumination solution, specifically, ReSTIR PT[1], within the NvRTX branch of Unreal Engine. A GDC presentation video on Zorah was released a few weeks ago.

Honestly something in the space between Figma, origami, framer and Cursor / v0 is gonna happen in the next few years and it’s gonna be wild.And what’s more, it’s in a blind spot. It won’t be an engineering led IDE and it won’t be a cool design tool for cool designers. It’s… https://t.co/fAusCTYN15— Ian Bach ☯︎ (@Ian8ach) November 27, 2024
