Sketchy Toon Shader (Unity URP)

Bring your scenes to life with a unique toon look that feels hand-drawn and alive.

Sketchy Toon Shader is a lightweight, fully customizable  Unity URP shader that recreates the expressive style of sketch animation. Bold outlines that subtly move, sharp cel-shaded lighting, and a textured ink finish that gives every model a tangible, illustrated feel.

This package is designed for artists and developers looking to add a distinctive, stylized presentation to their projects. Whether you’re creating a comic-book adventure, an experimental short, or a stylized 3D world, this shader gives your assets a handcrafted edge without sacrificing performance.

The shader is built entirely in HLSL for the Universal Render Pipeline and works out of the box with Unity 2022.3 and newer versions, including Unity 6.
