Can I extend an effect across segments and segments that are not adjacent?

Questions

I have an LED run around my deck railing outside and down the steps to the ground. The data runs in the order you see the segments listed below.

I’d like to have all of the “Wall” segments have one continuous effect (Back Wall, Long Wall, Short Wall, Side Wall) and then have the steps either have individual effects/colors or one continuous effect for the steps too.

How can I get an effect to span multiple segments and a segment that is not adjacent to others? The “Side Wall” is wired to be after the steps, so I have to skip those segments to have a continuous effect around the deck railing.

In my testing I can either get each segment to do the same effect but not in a continuous manner, or I need to set up 3 segments (the first walls, the steps, the final wall) instead of individual sections. This still means I have a gap that I can’t get an effect to cross though.

Is it possible to have a continuous effect with a large gap for the steps? If I could some how get all of the “Walls” into a single segment, that would probably solve the problem.

Hi @Mosquito Welcome
just select the segments yoiu like to use the effect on ARROW TOP LEFT
choose the EFFECT and thats it
SAFE Preset with chacked Segments only

!! ATENCHEN with ESP8266 only 8 SEGMENTS are Alowed in one preset !!

@Magig_Wled This doesn’t result in a continuous effect across the selected segments. Each individual segment runs the effect. For example, if I select Tetrix, instead of one string of lights “falling” to the other end, I get 4 individual sections with the effect.

You probably want to use a ledmap so that all your “walls” are contiguous and can be made into a single segment

Thanks for the pointer @kilrah . I found documentation on Mapping that I’ve read through. I’m not entirely sure if I’m understanding exactly what to do here. There is one sentence in the documentation that I’m unsure of how to handle

Use -1 in the map for gaps/blank/nul LEDs.

Since I want the steps to be a gap, should these be -1 or should they just be remapped to the end of the list of LEDs?

In my map, should I put the LEDs for the 4 walls and then the steps so it’s similar to this:

{"map":[
0,1,2,3,4, ... LEDS FOR BACK WALL
..., LEDS FOR LONG WALL
..., LEDS FOR SHORT WALL
..., LEDS FOR SIDE WALL
..., STEP 1
..., STEP 2,
..., STEP 3,
..., STEP 4,
..., STEP 5
]}

Or, should I be using -1 values for the Steps and only list the walls in the LED Map?

Yup. -1 means “there’s no actual LED here”.

You should avoid using -1 in ledmaps until you understand their behaviour.
