Hi francois,
Thanks for your replay. I got it to work in Prepar3Dv4 - however, as it is not a native P3Dv4 scenery, it does tend to stutter a little - and mybe some objects and vehicles are not shown correctly. For the most part it works as it is supposed to.
The process was rathter simple and pretty much the same as with Tongass Fjords. Copy the scenery - add the entrys to terrain.cfg - and place it in the right spot of the scenery libray.
I'm sure more experianced Simulator users are quite easily able to port it over as is - a full compatibility update to v4 would most likely require a complete remake of the scenery or better said a full recompile with the P3Dv4 SDK.
kind regards
