Offset start and end?

there’s a feature that adds a hardcoded mapping (see wled00/FX_fcn.cpp):

//enable custom per-LED mapping. This can allow for better effects on matrices or special displays
//#define WLED_CUSTOM_LED_MAPPING

#ifdef WLED_CUSTOM_LED_MAPPING
//this is just an example (30 LEDs). It will first set all even, then all uneven LEDs.
const uint16_t customMappingTable[] = {
  0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28,
  1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29};

//another example. Switches direction every 5 LEDs.
/*const uint16_t customMappingTable[] = {
  0, 1, 2, 3, 4, 9, 8, 7, 6, 5, 10, 11, 12, 13, 14,
  19, 18, 17, 16, 15, 20, 21, 22, 23, 24, 29, 28, 27, 26, 25};*/

you’d need to recompile the firmware after enabling/changing this.
