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:

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.

Smart Color Curves:

Make sweeping changes to your hue, saturation, and brightness, while preserving the maximum dynamic range of those values.

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.

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:

Pleased to report that my skeleton and I are cohabitating much better now.

We're having a few boundary issues but at least he'll always have my back.

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:

very grateful the moon is not actually made of cheese

Froze time so I could take a closer look at the raymarched material.

There's definitely a bug in my raymarching because the density changes when I pan up or down.

I also need to research if there are nice & fast distance field noise functions I can use to march in fewer steps.

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

Doing some raymarching in Unreal.

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