[](https://github.com/tbillington/bevy_toon_shader#license)

**Features**
- "Sun" color & direction
- Specular highlight
- Light banding
- Shadow casting
- Albedo map (base color texture)
**Not supported (yet)**
- Dynamic color banding amount
- Shadow receiving
- Rim lighting
## Installation
```sh
cargo add bevy_toon_shader
```
```rust
use bevy::prelude::*;
use bevy_toon_shader::{ToonShaderMainCamera, ToonShaderMaterial, ToonShaderPlugin, ToonShaderSun};
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_plugin(ToonShaderPlugin)
.add_systems(Startup, setup)
.run();
}
fn setup(
mut commands: Commands,
mut meshes: ResMut>,
mut toon_materials: ResMut>,
) {
// Camera
commands.spawn((
Camera3dBundle { /* ... */ },
ToonShaderMainCamera,
));
// Sun
commands.spawn((
DirectionalLightBundle { /* ... */ },
ToonShaderSun,
));
// Ambient light
commands.insert_resource(AmbientLight {
color: Color::GRAY * 0.2,
..default()
});
let material = toon_materials.add(ToonShaderMaterial::default());
// 3D object
commands.spawn(MaterialMeshBundle {
mesh: meshes.add(Mesh::try_from(shape::Torus::default()).unwrap()),
transform: Transform::from_xyz(0., 2., 0.),
material: toon_material,
..default()
});
}
```
