Hello,
please look at the attached log

Question : Do I need to rebuild the DB each time I change the "active" sceneries?
Not possible to build the DB for all sceneries prensent in the addon scenery folder?

I the log I find only a few "traffic" .bgls. in my opinion this is not complete because the ative scenery is Europe (see log) and I do not find all my European traffic .bgls.

If you are only changing the sceneries for traffic, then no. As I said before, Plan-G is only rteporting the traffic bgl because it found it. It doesn't actually use it. The next build will not report bgls that it doesn't use, so you won't see any traffic files.

It would be a bad thing just to blanket scan every folder in addon scenery, since many people have dupilcate copies, old version and all sorts of junk that is not "active". Many people do not use the addon scenery folder at all, and so scanning the active scenery list in scenery.cfg is really the only good way to proceed.
