Hi Umberto,
After loading 6 of the FSDT sceneries and 2 Flytampa sceneries (would seem with a v3 loader, appended with a patch after) I notice that when I look at the P3Dv4 world>scenery manager, the FSDT sceneries are on the top, located in order of loading(priority1-6) and while ticked as enabled, are grayed out, and unmovable as a block. The Flytampa sceneries are located(p7-11) not grayed out, and can be moved anywhere, other than above the FSDT sceneries.
I also notice from the Scenery Library, it shows the FSDT loader placed their sceneries in E:\Addon Manager\FsDreamTeam\CYVR\Scenery etc...while the FlyTampa loader placed theirs in: E:\P3D\FlyTampa\Sydney etc
Looking in Add-ons, I can see the 6 FSDT sceneries again, and able to ticked or unticked , but not change their priority.
While P3Dv4 can find both sets and they seem to work ok, one set of them aint right? and from your posts, it seems like the FlyTampa sceneries location is wrong? I notice several posts about the forums mentioning this issue and some confusion as to the correct place..Maybe there is really a significant difference and reason why the addon manager location is correct?
Anyway, hopefully, this will all become clearer as LM and the developers such as you, work out a correct procedure.
