I'm in the process of combining 8 Add-on vehicles (Planes and helicopters) into one dlcpack.
However, even after following Reyser's tutorial, Enhanced Native Trainer is giving the error "Can't find model XXXX" or "Invalid Model".
I have a feeling that it's due to many of the planes/helicopters having weapons as I had reached a point previously where I could spawn in the vehicles and fly them, but the weapons weren't working. It could be something wrong in one of the data files.
I've made my work thus far available to download from here: https://mega.nz/#!17BQkbqJ!1HOa-DrJWYZ4WfmujvfvpY8g08stObUiDWNXG_0Zawc
I'm running the most recent version of GTA V, and I'm running F7YO's gameconfig (Base).
Any and all help would be appreciated.
