How to make a Template for ANY Vehicle for Photoshop with Zmodeler 3?

Jayk0b

I am new to GTA Modding and i watched a bunch of YT Videos of how to create Templates but they are all not very beginner friendly.

Example: I want to make a custom livery for the Benefactor Feltzer, not a Police Car etc..

My Goal:
Creat my own template, bring it to photoshop, make a good lookin livery and have it ingame.
i already did this the past 3 years in Arma 3 but that is far easiert then GTA in my opinion ^^

Example from Arma3

Most videos JUST show how to download a template for Police Cars etc but i want be able to create a custom Car Skin for ANY car / Vehicle I want.

Thanks if anyone has any tips & tricks!
