How to add driver, passengers and loads to mod cars?

Hey guys, I'm trying to use the mod called "Driver, Passengers and Loads" on modded cars.

It works perfectly for normal (in-game) cars, but when I want to add them to modded cars, like a modded convertible Sunburst, I don't see the option in the "additional modification" vehicle configuration menu.

I've been trying to do this for quite a long time. So if anyone know how do achieve this, please let me know. Thanks

 

What version of beamNG is that?

 

v0.13

 

Why the hell are you running 0.13 anyway?

 

Be honest, you pirated the game

 

Not pirated. Downloaded

 

Thats the same thing.

 

To get more combability for some mods

 

Unless you bought the game aswell and downloaded that version that wouldnt really be an issue but if you haven’t bought the game it’s technically piratin’

 

Well I bought the game so how does this matter?

 

Where'd you buy the game from?

Oh wait you have the un-pirated version aswell, sorry

 

Ok thanks for the reply. But would you know how I could do it with newer mods like ETK series convertible?

If you want it to do in all versions, go to channel named bbtv ( or beambloxtv), there's a way to do this but it's kinda strange but it's only way
