I was playing around with some retro aesthetics for a 2D side-scroller project and wanted to get that cozy, worn-out look of old analog film. I couldn't find a single shader that did everything I wanted, so I ended up putting this one together.

It handles a bunch of features:

- Toggling between classic sepia, a warmer technicolor style, a washed-out faded look, and a grainy black-and-white mode.

- Animated film grain and vertical scratches that flicker at random.

- Procedural dust specks and curved hair fibers that pop up on random frames.

- Projector bulb flicker, subtle chromatic aberration, and lens distortion (barrel bulge).

To use it, just throw a ColorRect over your scene, set the mouse filter to Ignore, and apply this as a ShaderMaterial. All of the key settings (grain density, scratch speed, lens distortion strength, and colors) are exposed as parameters so you can tweak them directly in the inspector to fit your game's vibe.

Let me know if you run into any issues or have ideas on how to optimize it. Hope you find it useful!
