Hi,I have a lot of Bluesky sceneries working without any problem but in San Francisco area I can't have the scenery displayed well : there are tiles of ground all over the bay and also on the pacific shores.There is no other addon, the install of FSX is new, and I unzip and install Bluesky scenery by the numbers, What is wrong there?Thanks a lot for your helpPierreFrench Private Pilot

I haven't tried this specific one, but with most large freeware photosceneries, there is no water mask which means that the photoreal part will show over the actual FS water which is what this sounds like. Can you post an image?

Hello:I've not tinkered with that BlueSky scenery package in a long time, but I've seen the same thing flying up over the mountains from Half Moon Bay to SFO in FS9.IIRC, that particular BlueSky scenery uses a legacy FS8 or FS9 technique involving specially textured terrain polygons fitted to a specific terrain mesh made to be "paired" with the scenery tiles at a designated internal resolution.That method is I believe, the "VTP Photoreal" terrain technique discussed in various threads on the SBuilder for FS9 support forums.FYI: That particular BlueSky scenery has a fairly short visibility distance, and depending on the "shape" of the underlying 'active' FS terrain mesh loaded during one's flight, one may see edges of the textured terrain tiles ending at the outer aircraft terrain LOD-based visual display radius, with other terrain surfaces showing underneath.IIUC, that VTP method maps textures onto a BMP and/or BSQ raster image as "fixed shape" (non-mesh-clinging) triangles, and thereby creates a "digital terrain surface" ...fitted to the specific and matched terrain mesh which is also made at the same time.Use of a default or 3rd party mesh different than the original "paired" terrain mesh may allow such visual display anomalies to be seen.IIRC, the maximum resolution of the "paired" terrain mesh made via the VTP method described above was LOD-8.AFAIK, if one wishes to position the "paired" terrain mesh file to take display priority over other default or 3rd party add-on terrain mesh files, one must place the paired mesh in a FS Scenery Library "Area Layer" which is as low as possible in the stack of layers seen in that FS Scenery Library GUI; this is because mesh priority assignment works "backwards" in FS9 compared to other versions of FS.BTW: In FS9, if there is 'priority contention' between other terrain meshes with a matching or higher compiled internal resolution in the same folder and its associated FS Scenery Library "Area Layer", one must rename the mesh with desired top display priority via a specific "Alphabetical" naming procedure.Possibly Scott Smart (aka "scott967") or others who know more about this somewhat obscure type of scenery might offer additional comment and explanation of a workaround, and how the "Alphabetical" naming system must be implemented to achieve display priority of such FS scenery files, and add-on terrain mesh in general ? Hope this helps ! GaryGB

Problem solved by Philippe on french avsim forum : when removing all files *_SX.bgl evrything runs fine.Thanks to everybodySeason greetingsPierreEssaie de sortir tous les fichiers du type *_SX.bgl (en les sauvegardant qque part, of course) du répertoire /scenery. de BlueSky. Cela devrait aider.Philippe
