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.

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: 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!

Rendering Particles with Compute Shaders
Overview I developed a technique to render single-pixel particles (using additive blending) with compute shaders rather than the usual fixed-function rasterization with vertex and fragment shaders. My approach runs 31–350% faster than rasterization on the cases I tested and is particularly faster for some “pathological” cases (which for my application are not actually that uncommon). I observed these speedups on both NVIDIA and AMD GPUs. Using this technique allowed me to ship an app that runs on minimum-spec hardware without sacrificing visual fidelity.

okay here it is all wrapped up — my recreation of Baldur's Gate III's occlusion cutout effect in Unreal! i learned a LOT from this experiment over the past couple days, and will share some breakdown bits in the 🧵 shortly! #gamedev #shaders #unrealengine
It's possible to change UI contrast in Unreal Engine: Change `GSlateContrast` from C++, or `Slate.Contrast` from the cheat console. Maybe an easy accessibility win to add to your game? #UnrealEngine
