• Introduction

BoBiCo Shader is a feature-rich shader for the S&box game engine, inspired by popular shaders such as LilToon and Poiyomi while introducing its own optimized and flexible rendering systems.

Designed to be both easy to use and highly customizable, it supports a wide range of artistic styles, from stylized toon rendering to realistic PBR workflows, all while keeping performance in mind.

• Feature Highlights

- 🎨 Multiple Shading Styles

BoBiCo Shader comes with six built-in shading modes: Flat, Multilayer, Texture Ramp, Shade Map, Realistic, and Fur.

Every shading mode also supports Wrap Shading, allowing you to easily achieve different lighting styles without switching to another shader.

------------------------------------------------------------------------------------------------------------------

- 🪟 Flexible Rendering Modes

Supports Opaque, Cutout, and Transparent rendering pipelines, alongside advanced transparency techniques such as Dither Alpha, Alpha-to-Coverage, and Fresnel Alpha.

The shader intelligently reuses existing alpha channels whenever possible, reducing the need for dedicated masking textures.

------------------------------------------------------------------------------------------------------------------

-💡 Full Lighting Support

Designed to integrate seamlessly with the S&box lighting pipeline, supporting Direct Lighting, Indirect Lighting, Light Probes, and DDGI.

Lighting transitions adapt naturally to the environment while preserving the intended visual style.

------------------------------------------------------------------------------------------------------------------

- 🎛️ Extensive Material Customization

Build highly customizable materials using dual main color layers, built-in decal tools, normal maps, emission, matcaps, and a large collection of color adjustment controls.

Whether you're creating stylized or realistic materials, the shader provides plenty of flexibility without becoming difficult to use.

------------------------------------------------------------------------------------------------------------------

-✨ Stylized Effects

Enhance your visuals with built-in features including MatCaps, Inverted Hull Outlines, Glitter Effects, and several additional NPR-oriented rendering options.

------------------------------------------------------------------------------------------------------------------

-⚙️ Physically Based Rendering

Every shading mode except Fur supports a complete PBR workflow, including advanced material parameters and flexible multi-channel controls for fine-tuning surface appearance.

------------------------------------------------------------------------------------------------------------------

-🚀 Advanced Features

BoBiCo Shader also includes support for Screen Space Ambient Occlusion (SSAO), Parallax Occlusion Mapping, Self Shadowing, Subsurface Scattering, Fur Rendering, and many other advanced rendering techniques.
