Chaos Eye Shader

An eye shader based on chaos theory. The appearance evolves smoothly over time and exactly repeats once every 24 days.

Long-form demo: https://youtu.be/cEXAURKKZrU

Features:

• Parameters of iterated function are configurable. These heavily influence its appearance.
• Shader can be positioned and scaled to any point in the UV map and left-right symmetrized.
  • If you need some other way of positioning, ping me on my Discord!
• Animation speed is configurable and may be disabled.
• Glitter size, amount, speed, mask, and brightness are configurable. Glitter may also be disabled.
• Optional eye texture.
• Optional cubemap override.
• Matcap support.

Performance:

• 1 material slot.
• Measured at 1.6 milliseconds per frame at 4K on my PC.

As a custom shader, this is PC only.

Must have some experience with Unity.
