The latter would make it non-modular. The whole purpose of modular is that you can copy and paste to \ACTIVE, so you probably want to make a copy of your current livery, located in the Modular folder, and then edit it so you can switch them on and off through moving folders in "_MODULAR_MODS". Changing common_fom.erp will make it 'permanently'.Guys, if I use a modular version of a MyTeam livery and I wanna add another livery for variety so I can switch between them ingame, and since most mods changes the default livery so I wanna replace for eg. The Miami skin(Epic_03) with another dds livery skin through EGO ERP, do I have to edit the erp file in the ACTIVE modular folder or go to assets/2022vehiclepackage/teams/commonfom.erp and edit it from there. I'm still new to this modular process of modding since I've been using manual installation with Ego since F12020. Thanks in advance.
