Hey sorry I’m pretty newb still when it comes to this, but I just got some new PEDs for LSPD and they have the option to customize patches and ranks insignias.
But its not an option on the skinshop.
I don’t really know what info I may need to give you guys in hopes of getting the help I need 
But the PED is: https://www.gta5-mods.com/player/new-lspd-cop-m-oiv-v1
Thanks in advance for any help 
Just extract the .ydd .yft .ymt .ytd files to a stream folder then seach in vrp\cfg\cloakrooms.lua the models to load
