Hello I am trying to make an object which slowly cycles through colors along the x (width) dimension of the object. I already have the color ramp set up as per below, but I dont quite understand how to make the colours cycle through and loop around to produce a smooth animation. I currently have this:
Can someone have a look and tell me where to go from here? I am assuming sine or cosine must be used to shift the colours through but how?
