Best Way to Create a Radial Gradient

[Rob Ot]

Hi everyone, I was wondering how to create a radial gradient material? I want something like a flame, going from red to orange.

Thanks in advance!

That kinda sounds like the lava shader forge:

Also maybe the looping patters:

Or maybe an eye:

Hi Rob, I think you are looking for a Spherical Gradient (or Circular, if you remove one dimension), something like:

(You want a gradient along the radius of a circle, but radial means a gradient ‘along the radians’, so , going from 0 to 2 Pi…)

Alternatively (what I would prefer to use), there is a Vector Math > Length Node:

Dangs I’m taking note of this.

You could even add noise to the vector, change it to 4d and animate the w channel.
