This technique rebuilds the image by mixing color layers with MixBox lerping — a powerful color grading method that lets you target specific hues. Each layer defines a color gamut, and the algorithm picks the closest match to the desired color.

Watercolor shaders often look too digital, using Mixbox-inspired pigments makes them feel natural, like real paint on paper.

Crosshatching + Mixbox mixing = pigment-like rendering. 🎨
The hard part? Deciding how much of each color to layer.
We use golden section search to minimize the error and make the final result match the image we want

When quantizing color in stylized effects, one problem is how bad the greens look. Computer green is the most annatural color (followed by computer magenta). A cheap trick to combat this is to simply shift greens towards yellow or cyan.

📐 How to describe shapes in games: geometry for game effects ✨
Geometry is at the heart of game development — from logic and AI to physics and visual effects. In this we go over the most common ways to describe shapes in games and how they’re used to build compelling effects. 00:00 - Intro 01:56 - Shape operations 06:30 - Sets 09:59 - Equations 12:13 - Inequalities 13:17 - Membership functions 16:02 - Signed distance functions 21:15 - Outro 🎮 Whether you're working with procedural meshes, splines, particle systems, or SDFs, this video will give you a clearer understanding of: 🔹 Shape operations (Boolean, Minkowski sum/difference) 🔹 Ways to describe shapes: sets, equations, inequalities, membership functions, SDFs 🔹 How the descriptions relate to each other 🔹 Practical use cases in visual effects and game mechanics 🔹 The math that powers outlines, masks, deformations, and more We dive deep into the structure behind how shapes are defined and manipulated — an essential...

Box blur basics
Easy to write, but slows down quickly as the blur size increases.
The fix? Use two passes, one horizontal, one vertical.
Same result
Much better performance
These are called separable operations.

These variations all come from the same base effect, layered lines, rotated and combined to simulate shadow and texture.
Small changes in angle, spacing, or texture = totally different feel.
