I installed the VH-VFH which was report not working, it has no model.JST folder inside the SimObjects folder and not model entry in the cfg. After unticking and ticking the Seated Passengers Airplanes setting, it was scanned by FSDT and the model folder was added.
That did not happen with the 3rd party livery from 9H-LMI, wether it was linked or directly installed in the community folder.
They just released a version 3.0.1 - and I am currently downloading it.
