While many shaders exist, they generally fall into two categories: standalone lightweight effects and modules for high-end rendering engines.
Toon shaders in MikuMikuDance (MMD) are specialized MikuMikuEffect (MME) scripts that transform 3D models into 2D, anime-style visuals by simplifying light gradients into flat blocks of color. Core Toon Shading Options toon shader mmd
toon shaders, several research papers and technical documents cover the underlying techniques used in the MMD community (such as "Ray-MMD" or "PAToon") and the general evolution of toon shading. Key Technical Papers and Surveys While many shaders exist, they generally fall into
Light creates a smooth gradient from bright white to deep black. Skin looks soft and oily; metals look reflective. While many shaders exist
