I’m trying to create a horizontal gradient that appears to move along the horizontal axis, and repeats continuously as if there is no join.
For example, from left to right, a red to purple, then back to red again, that appears to move across the screen in a line.
I can sort of do the effect by adding a hue rotate effect, and animating the rotation, but the widths of the bands of gradients seem to change size as the colours “move along”.
