    Best Way to Create a Radial Gradient

    Question Materials and Textures
    Rob Ot(modelmonkey)

    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:

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