Hey Albert, this seems to be a weird quirk in Blender, discovered here: https://blog.cgcookie.com/forums/topic/not-working-on-just-my-regular-mesh/
If anyone else has an issue with the “Spiral” Setting not working, I’ve found a fix:
1. After changing “Hair Length” to “0.1” in tutorial, go to the top of your particle settings and check the “Advanced” box
2. Scroll down to your “Velocity” options and change the “Random” setting to “0.01”
3. Resume tutorial where you left off; You’re good to go!
Hope this helps!
