It should work. Check out this [post](https://wled.discourse.group/t/addressable-icicles-tutorial/9920/14). I was taught in it. You don’t need a map file. You only need the Gap file. You need to download it here.

It is done in any text editor (Notepad++). Copy directly what I pasted below.

[0,0,0,0,0,0,-1,-1,-1,-1,-1,-1,0,0,0,0,0,0,-1,-1,-1,-1,-1,-1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,  
1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]  
And save it in json format (select Sintax from the editor menu) with the name 2d-gaps (required). UTF-8 encoding. This should work for 2 (if there are more matrices, then the file needs to be redone, I wrote above how to do this) your matrices. Just check it out. And you will only need one controller.
