It might be interesting how I installed my ship traffic:
P3Dv4 allows registering folders outside the main folder "Prepar3D v4". This way a better a better overview is given.
So all of my ships traffic (RTMM and the Global Ship Traffic by Henrick Nielsen is in an "Addon Ships" folder,
separated by name:
- RTMM AI Shipping
- Global AI Shipping
These folders contain all necessary subfolders like \effect, \sound, \Global AI Traffic (the traffic files) and \SimObjects\Boats and so on.
Everything is registered as suggested by Lockheed Martin and works perfectly.
This way no original effects, sound and whatever is overwritten.
