Hope one of them gonna see my post. Thanks anyway dude, you confirmed what I feared the most but I motivated to learn how to do that

Hi everyone and before anything, I'd like to thank everybody because I can't count how many times you guys helped me just by reading your posts.

However I haven't found almost anything about the subject I'm about to talk.

So I'm a webdesigner and I really enjoy creating liveries for my server. But here's the problem :

We have a lot of modded vehicles that hasn't have any livery, nor _sign in the .ytd and can't see anything through my menu. I've tried to add the _has_livery and adding a custom sign_1 in the .ytd but without any success.

I'm guessing I've to edit them in Zmodeler or something like that but there's no tutorial, nothing to explain how to do that.

If you guys got the solution, that'd be awesome and you would make 32+ players happy af!

Thanks again.
Fecale.
