Help in achieving the effect

Is there a ready project for the effect of running/flowing light?
I searched on Google and people were looking for such an effect, I did not find a clear answer on how to handle it.
I already have an ESP32 driver with WLED and I would like to get such an effect

Thanks for your helpful suggestions

hi @pako
use 2segments left right
make them chase
make the time of preset as long to fill the Stripe
then make preset for both Solid to make it Stop as long as you wand it to be FULL ON
then use the Effect CHASE 2 with a Reverse Segments in first step
preset time as long as you need to return from last led to first

(1) Create a Wipe preset with Fx color whatever color you want to wipe ON and the Bg color black.
(2) Create a solid preset with the Fx color from the first preset above.
(3) Create a preset with Fx color black and Bg color whatever Fx color you had in the above preset and set the segment to reverse direction.
(4) Create an off preset or solid color black.

Create a playlist with the first entry as preset(1)
Set it’s duration to however long you need it to run to fill your LEDs.

Next: Option 1 or 2:

Option 1: If you want the lights to stay ON until another trigger to turn them off:
Add End preset(2)

Option 2: If you want the lights to wipe back OFF after set time:
Add second preset(2) and set it’s duration
Add third preset(3) and set it’s duration
Add End preset(4).

If you chose Option 1 and now you want to wipe the lights back OFF with a new triggered event:

Create a New playlist
Add preset(3) and set it’s duration
Add End preset(4).
