Animated Gradient Node? I'm working on a knob with some LEDs around it.
When the knob is all the way at 0-position only the top and bottom LEDs are on and when all the way to the right 100% all the LEDs will be on.
(the LEDs are just an image texture with some bump. With one node of a turned-off LED and one node of a LED material that is glowing.)
The way I'm planning on animating this effect is to have a Gradient node controlling the mix fac of a Mix node. My question is how do I get the gradient &quot;butterfly pattern&quot; of the mix fac?

Pic 1, the knob at 0, top and bottom LEDs are on
Pic 2, the knob at 50%
Pic 3, the way the knob looks.
Not sure if i understood the request correctly, but that's the result (don't know if I'm allowed to post gifs):


And that's the nodes:
