Toonifier – Stylized Toon & Cel Shader for URP

Toonifier is a stylized shader and material system for Unity 6 URP. Create bold cel-shaded characters, colorful props, and expressive environments using intuitive material controls—without writing shader code.

Build your style with flat colors, crisp lighting bands, or custom shading ramps. Add highlights, rims, gradients, and per-object outlines, then combine them with your own textures.

Features

• Flexible cel shading: flat, single-cel, stepped, and custom curve-ramp lighting, plus an extra colored shadow layer.
• Per-object outlines: adjustable pixel-based width, color, and opacity, rendered through the included URP Renderer Feature.
• Stylized highlights: configurable specular, camera-dependent View Rim, and camera-independent directional Light Rim.
• Height gradients and vertex colors: add color variation in local or world space.
• Texture controls: albedo, detail, normal, emission, and material ambient occlusion maps.
• Art-directed lighting: control light-color influence, override the stylized main-light direction, and customize received shadows.
• Transparency and cutouts: Alpha, Premultiply, Additive, and Multiply blending, alpha clipping, and face-culling controls.
• Material workflow: custom inspector, ramp-texture creation

Two shader options

ToonShader provides the full feature set, including additional per-pixel lights, soft-shadow support, and optional URP SSAO.

Mobile Fast offers a reduced-cost alternative with one main light, hard shadows, and no additional-light shading or SSAO. It retains the artistic controls, textures, material AO, transparency, and optional outlines. A matching URP pipeline configuration is included.

Included

Two feature-demo scenes, example materials and textures, the outline Renderer Feature, and a detailed user guide covering setup, controls, scripting, and troubleshooting.

Requirements and compatibility

Requires Unity 6 with URP. Tested with Unity 6000.0.47f1 and URP 17.0.4. Other Unity 6 versions have not yet been verified. Built-in Render Pipeline and HDRP are not supported.

Outlines require the included Renderer Feature to be installed on the active URP renderer. Mobile Fast reuses passes from the full shader, so both shader files must remain included. Mobile performance depends on the device and scene; physical Android and iPhone performance has not yet been validated.
