6 drop-in 2D sprite shaders for Unity, free, built for pixel art. Put any of them on a SpriteRenderer with one line of C#, or as a material from the inspector.

• Unity 6.3 or later, in any render pipeline: Built-in, URP (2D or Universal Renderer) or HDRP.
• A Documentation.txt in the package's folder says what is where and how to use it.

SpriteFX.Flash(player); // hit flash, own material back after
yield return SpriteFX.DissolveOut(enemy).Wait(); // then Destroy(enemy.gameObject)
SpriteFX.Apply(coin, "shine");

What's inside

• flash: hit flash to any colour
• outline: pixel-perfect, outside or inside, 1–16 px
• dissolve: noise or directional, with a glowing edge
• shine: a sweeping highlight for pickups
• blink: invincibility frames
• hue shift: static or rainbow cycling
• Every setting is a slider in the material's inspector, with sensible defaults.
• SpriteFX helper: Flash, Blink, DissolveOut/In, or animate any setting with Animate(...). Effects give your own material back when done.
• Demo scene with every effect running; click a sprite to hit it.

Compatibility

• Unity 6.3 or later, in any render pipeline: Built-in, URP (2D or Universal Renderer) and HDRP.
• Either input handler for the demo: the Input Manager or the Input System.

The shaders, the package's C# scripts and the Python code that draws the demo's sprites pixel by pixel were written with the help of AI (Anthropic's Claude); no generative image model.
