I made a hypno spiral shader for a future project and decided to release it by itself for free, so enjoy!

Note: This is a GENERIC asset and can be used in any type of Unity project.

Dgn Ely's Hypno Shader is a free, mostly simple hypnotic spiral shader for Unity, with several customization options.

Full feature list:

• Pick any two colors for your spiral, with independent transparency
• Choose the spiral's direction, number of arms, and how much they wrap around the spiral
• Add a "color swap" ring with 4 different modes and 4 more customization sliders
• Use the shader on a plain plane or the included cone

Requirements:

• Unity 2019 or later
