Godot-MToon-Shader is meant to implement the same functionality and featureset as https://github.com/Santarh/MToon used in the VRM standard.

This addon is designed to be used together with https://github.com/V-Sekai/godot-vrm but may also be used as a standalone toon shader.

This version of MToon only supports Godot 4.0 and newer. To use MToon on Godot 3.x, use the godot3 branch of godot-vrm, or download it from the Asset Library.

Installation

Godot 4.0 or newer

Install this addon by cloning this repository into the addons folder, or using git submodule - If used together with godot-vrm, it is critical that this repository be at addons/Godot-MToon-Shader within your Godot project.

To use the proper shader inspector, enable the MToon plugin in Project Settings -> Plugins -> Godot-MToon-Shader.

It is recommended to install godot-vrm or from the Asset Library once it becomes available there for 4.0

Godot 3.x

This repository does not support versions prior to Godot 4.0

For VRM and MToon compatible with Godot Engine 3.2.2 or later, use the godot3 branch of the godot-vrm repository.

Known issues

Caveat: Scenes with realtime omni or spot lights will have clustering artifacts, because there is no current way to detect if a given light is directional. After some missing variables are added, we can provide a way to detect this.
