Guide for dynamically changing armor with attach points

[blackninja50]

Dose anyone know of a guide for changing armor appearance with attach points? I'm trying to add attachable pins to hats via attach points with no luck

 

see here (https://forums.nexusmods.com/index.php?/topic/6640021-help-with-custom-armor%EF%BF%BD-attach-points%EF%BF%BD/)

 

So i'm wondering if there's a guide out there showing how to do this.
