# Bevy Film Grain Shader

A film grain post process shader implementation for the [Bevy game engine](https://bevyengine.org).

It can be used with a single camera or multiple.

It's tested to work on desktop and the web with WebGL 2.

WebGPU on the web should work but I haven't tested it yet.

Expect changes in the future as there are missing features such as changing the size of the noise and animating the noise over time.

## Minimal Example

```rust

use bevy::prelude::*;

use bevy_mod_film_grain::{FilmGrainPlugin, FilmGrainSettings};

fn main() {

    App::new()

        .add_plugins((DefaultPlugins, FilmGrainPlugin))

        .add_systems(Startup, setup)

        .run();

}

fn setup(mut commands: Commands) {

    commands.spawn((

        Camera3dBundle::default(),

        // Adding this component enables the effect for this camera only.

        FilmGrainSettings::from_strength(0.2),

    ));

}

```

## HDR

If your camera has hdr enabled, you will need to enable the hdr feature on this crate. Eventually I'll figure out specialization so this isn't needed.
