A look into making Spiral Materials for VFX & beyond, like space scenes.
This is how it looks made. Note removing the Sine will make it animate in 1 direction.

So I found this material https://www.artstation.com/artwork/eJP3WG on Nicklaus McHugh Artstation which was very similar to how I was making my material, So gave it a try. Give him a like if you like this material as it came from his work!
So this is what you get basically with the OG material - Some adjustments required.
This is tuned, Effect 1.
This is tuned, Effect 2. Works well with a BP.
Texture change to suit the scene.
