Advanced Cel Shader & Outline - Stylized Post Process Material is a complete solution for achieving high-quality anime, comic, and stylized toon visuals in Unreal Engine.

It features a highly optimized master post-process material utilizing HLSL custom nodes to ensure high performance. The shader intelligently reads the G-Buffer to correctly handle complex scene elements out of the box, without requiring Custom Stencil setups. The cel shader fully supports Emissive materials, completely preserving the native Unreal Engine bloom. Furthermore, Metallic and highly reflective objects, as well as the Sky, receive a specialized toon shading via Luminance Posterization. This ensures they maintain their reflective properties and blend perfectly into the stylized aesthetic. Additionally, unlike standard cel shaders, this material ensures that Point Lights, Spot Lights, and directional lighting completely retain their original colors and bounce light.

The system gives you full control over your lighting setup. You can easily adjust the number of Shading Tones to create anything from hard binary shadows to soft painterly transitions. The material also features a customizable Rim Light for character highlighting and an integrated Outline pass based on depth and normals. Designed for a simple workflow, the pack includes 6 ready-to-use Material Instances, covering presets like standard 3-Tone, hard 2-Tone, soft 5-Tone, and fully desaturated grayscale setups.
