## Installation

### Using git URL in Cargo.toml
```toml
[dependencies.grex_outline_post_process]
git = "https://github.com/exvacuum/grex_outline_post_process.git"
```

## Usage

In `main.rs`:
```rs
use bevy::prelude::*;
use grex_outline_post_process;

fn main() {
    App::new()
        .add_plugins((
            DefaultPlugins,
            grex_outline_post_process::OutlinePostProcessPlugin,
        ))
        .insert_resource(Msaa::Off)
        .run();
}
```

When spawning a camera:
```rs
commands.spawn((
    // Camera3dBundle...
    NormalPrepass,
    grex_outline_post_process::components::OutlinePostProcessSettings {
        weight: 2.0,
        threshold: 0.0,
    }
));
```

This effect will only run for cameras which contain this component.
