Add-on vehicles help

So for my server I try to make add on cars using OpenIV and vMenu and I create the mod folder with the stream folder which has the yft files and the data file which has the .meta files and then the __resource.lua and put it in the server.cfg and in the vMenu config and the server loads the resource but when I try to spawn the vehicle through vMenu it has the vehicle in the unavailable vehicles so I cannot spawn it.

Ensure your streaming the files correctly. It sounds like vMenu cannot find the car your trying to stream because you haven’t installed it properly (<-- The custom vehicle(s))
