WIP How do I make a skin for both the h45 cargo box and the van body?

I've tried two methods but both of them don't work. Help is absolutely appreciated.

Specifically, a moving company skin for the cargo box, the dryvan, and the van body.

 

Hello, have you tried from Youtube, an tutorial? If you don't, here :

 

I have tried the youtube video, but I'm still trying to find a way to make a skin for both the van and the cargo box since it's just a part.

 

I can't help you with this, please visit the WIKI and search how to make skin on Van.

 

I wouldn’t even bother with the wiki because it’s not helpful except for basic explanation. Try and contact a modder and see if they can help out!

 

Erhm...You can contact BeamNG Staff and tell them, how it will works. Sorry, I can't help.

 

Alright.
