Hello Martien
In case you are still interested in doing the Air Zermatt livery ...
I just pushed all necessary additions for adding the
HB-ZAZ Air Zermatt version to the ec130 development repository in gitlab
Right now it is just a white livery with 4096x2048px in Models/Liveries subdirectory, with the painting-independent texture elements.
Please see the FG-Wiki EC130 page
http://wiki.flightgear.org/Eurocopter_EC130_B4 and the development repository link (
https://gitlab.com/mhab/ec130) ...
Best would be to create a fork in gitlab, push the new livery and create a merge request when you are done
Remark: I really recommend to design the livery in 4096x2048 and push it that size to the "Resources" subdirectory.
The 2048x1024 downsized livery would go to the Models/Liveries directory for final release ...
Note: If I don't get news from you, I may start it myself in near future ...
