Enhancements
1

If you want to change the ledmaps on the fly to work with apps like xlights , then there is an easy way
Just create and save a ledmap under wled-ip/edit with the name of ledmap1.json

Then add “ledmap”:1 to your presets and call the preset

below is an example of a led map for a serpentine -style 16x16 matrix mapping

{“map”:[15,14,13,12,11,10,9,8,7,6,5,4,3,2,1,0,

Be warned that ledmaps created in this way support about 800 entries.
More and WLED may become unstable or crash.

I was half way the 1k map and just going to share it ,thanks for the heads up

Where in the preset do you define “ledmap”:1?
I get JSON syntax errors when I try to include this.

Or do I need to be using this fork?

You can wait for official release sometime in July or use a binary from @srg74 who compiles my fork and provides binaries for various set-ups.

You can, as well, just add "ledmap":1, immediately after first curly brace { in API window. Don’t forget the comma.

Good luck , While i faced no issues with 512 leds please to note the caution about the 800 limit

Thanks, working and I only have 144 leds so no issue with the limit.
Mappings working well between presets. May have found another issue but taking that into the beta discussion on Discord.
