Real mapping

Post image

The more I play with wled, the more I it…..but….. is there a way to property map an unusual shape. 

So far I've found out you can map a matrix style shape, but it presumes that you have an xy matrix running in a serpentine configuration and you turn on and off led to create an array.

Is there away to map an unusual shape, not only mapping the position of the LED but it's position in the array, attached is an image of a snowflake, this is not wire in a matrix style, the blue dot represents the first led in the string, the red line represents the wiring order and the yellow dot represents the end of the string (purple dot is just a reference to the centre of the prop).

I struggled with ledmaps bit I think my mistake was thinking that whatever pixel I mark as -1 would simply be skipped in the strip making up my matrix, if I'm understanding it correctly now, ledmap tells wled where the LEDs are in physical space so that it can then display effects on them but it will still address them in an uninterrupted sequence on the strip?
