Issue with livery (zmodeler)

[Haazey]

Hello there having issues installing a livery.

I have a car that doesn't have a livery so i took it into zmodeler and made a template & then made a livery for it.
I've imported the livery into openiv and it hasn't done anything

all help is very appreciated.
my discord is Haazey#9139 if you feel its easier to talk there
