it seems that CPPM3 (which haves it's own PM menu) can't change for the custom one with the enforcement enabled, if you enable the custom model from the CAC menu on C key nothing will happens, if you use the regular PM Menu (this one) it will have the color pallet of the CAC menu, but with randomized features (gender, race, hair, etc...) if you go to the Q key and sellect apply PM from there, the play will respawn like CPPM3 intended to, but with a complelely white version of the default CC, going back to the CAC menu and apply it again displayed the OC properly for me, but I can't tell if will show it normally for everyone else because I can't test it at the moment
also, I heard PPM2 weorks better with this addon, but CPPM3 is far better and less bugging
