Why do the first and last layer / column light up at the same time

Im playing with a 3d RBG led cube but I’ve noticed that the first and last layer or columns are lighting up at the same time even. Im guessing its something to do with how the ramp works

Hi @InvisiBug,

when stepping through it, frame by frame, you can see that when the ramp cycles there is blue at the bottom and the top of the texture:

Since the channels used as the lookup uv channels in the TOP To CHOP go from 0 to 1 and include 0 and 1, if the ramp is visible on both ends, top and bottom of the cube simulation will light up.

Also check out how LEDs can be controlled with our new POP family but looking at the relevant OPSnippets.

Hope this helps
cheers

Heya, thanks for this great response :slight_smile:
How do you step through frame by frame?

Hi @InvisiBug,

the left and right keyboard keys will pause the timeline and step through the timeline frame by frame.
