I just released Enhanced Chromatic Aberration for Unreal Engine! Get high quality multisampling camera lens refraction inside the engine. Achieve filmic style with smooth blending and a full spectrum of colors:

As a bonus, I'm also including Chromatic Aberrated Glass, a collection of exotic translucent materials that refract light in ways you've never seen before:

Unreal like most games does aberration by just splitting and the RGB channels. This produces hard edges and only extracts a few colors at a time. Enhanced Chromatic Aberration is on the bottom. You can see it extracts a full prismatic color spectrum with smooth lensing:

CHROMIA exotic color grading for Unreal Engine is now available! I made CHROMIA to help create bold, opinionated looks for games or cinematics. Here's what it can do for you:

Exotic color correlations: Modulate your colors in ways you never thought possible. Give an iridescent glow to your shiniest surfaces, or make creeping polychrome shadows.

Tricolor Palettizer: Choose a tricolor visual identity and shape your image around it. Shift colors towards your palette, or emphasize colors that already match it. CHROMIA uses the Oklab perceptual color space to make your color transitions silky.

Great puzzle games have a kinky kind of dom-sub flirtation thing going on where they dangle puzzles and solutions right in your face where they know you can't see them. The naughtiest most sexual game I've ever played is The Witness. M-rated stuff, 100% not for kids.

Blue Prince is probably #2. It's got me all hot and bothered which is why I can't stop posting about it.

The thing I hate about Blue Prince is that the more I play Blue Prince the more I love Blue Prince and yet I would love Blue Prince more if I could play Blue Prince less while trying to play Blue Prince Blue Prince players know what I'm talking about

Here's the much-cheaper way to fade a shadow for these raymarched materials: Dithered shadows! They're not especially convincing but let you skip raymarching in the shadow pass entirely.

Raymarching updates: I used Inigo Quilez's blog (link below) to rewrite the raymarched material using fractal SDF noise. Now I'm trying to make it play nicely with Unreal's lighting. This is using shadow maps, with automatic cache invalidation enabled:

This is EXPENSIVE! Like, unusably expensive. Every single light needs to repeat the raymarching in the shadow pass. Even with just the directional light, on RTX 4090: Shadows on: 40 FPS Shadows off: 120 FPS I've got a reasonable (if less pretty) approach I'll post later.

Source control should be the first thing a computer science curriculum teaches. When you can barely code, losing working code is backbreaking. Every day I see someone lose work. Don't even start with code. Write some haikus, change them, then look at your diffs and revert.

An "octave" is a 2:1 frequency ratio, named after the 8 notes it contains after crossing 7 diatonic notes arbitrarily chosen from the 12 tone equal-tempered scale. Worst name ever.

Raymarching improvements: - Take big steps until we cross the noise threshold - Binary search smaller steps to approach the exact threshold - Estimate normal via finite difference

I'm a ways off from going back to work on the 4D game but this is how I'd like to render objects entering or exiting your 3D cross-section.

Doing some raymarching in Unreal. We get self-shadowed lighting by using a masked material, inferring normals, and providing a pixel depth offset.

A common failure mode when people ask for programming help is not knowing what ingredients are required to solve a problem. No description of what they were doing Or what they expect Or even what's happening now And this reveals how people solve all kinds of life problems.
