  • Change the ramp type to Four Corner Ramp.
  • Create four different colors for the ramp: red, yellow, green, and blue.

Info

You can change how the image is remapped by adjusting the HSV values of the ramp.

  • Connect a file or Noise texture noise shader to the Color Offset color_offset of the Ramp rampRGB. This will drive the distortion effect.
Tip

You could also add a Range range or Remap remap shader in between the file texture and the ramp to further control the effect.
