Ultimate Toonshader Generator (Eevee) is a Blender add-on from RUIDO VFX for creating toon, anime, and 2D-style shading directly in Blender. It generates stylized toon shaders quickly and lets you customize lighting and shadows, apply consistent looks across multiple objects, and work in a fast, non-destructive way. The add-on targets Blender's Eevee render engine.
You get 10 built-in toon shader presets and a randomize button for instant variations. Full control over light, shadow, range, and intensity is available, and the add-on supports image textures, flat colors, and alpha textures. An index selector lets you control multiple shaders independently.
The download comes as an add-on packaged in a .zip file that's ready to install, along with an installation guide and user instructions. It works with Blender 5 and up and is also compatible from Blender 4.2 onward, covering the 4.2 to 5.2 range, and is distributed under the GPL license.
