World Scenery 3.0

World Scenery 3.0 is a project to replace the tiled single-mesh World Scenery 2.0 with an LoD-based approach using a regular elevation mesh, landclass texture and vector line features.

This leverages OSG's Virtual Planet Builder and OpenStreetmap APIs.

Currently Available Scenery

Terrain

Scenery is currently not distributed using the official Terrasync, Nia provides a terrasync compatible download, point your terrasync client to https://de1mirror.flightgear.org/ws3/ to make use of it. As of writing (2024-01-15) it contains all of the sceneries below (duplicates removed) and will get updated when a new Airports package is made and when Wayne provides her with new US scenery. If you don't wanna deal with changing your terrasync settings, you can always download sections of scenery via the links individually and added to your scenery path. If you set these in your scenery path ahead of any other scenery, it will pick up osm2city, scenery objects etc. from the underlying scenery as well.

Airports

In addition to the selected areas above, global up-to-date WS3.0 airports have been built. You can find them here

Scenery Files Placement

Uncompress the downloaded scenery files into a folder of your choice, such as E:\MySceneryFolder. To be recognized by FlightGear, the selected scenery (from the table above) must be located in a folder with a "vpb" subfolder, such as (EX: C:\mysceneryfolder\hawaii\vpb). The scenery files above are compressed and include the "vpb" folder.

Installing

Using the FlightGear FlightGear_Qt_launcher both the terrain and the airport are "installed" by going to tab "Add-ons" and then add the respective folders to "Additional scenery folders". When adding an additional scenery folder, you need to point to the folder immediately above the "vpb" subfolder.

If you add the airports the first time you might have to close the launcher and reopen it again to get the navigation data loaded properly into the session.

Running World Scenery 3.0

To run WS3.0 you need to set the /scenery/use-vpb property to true at startup. Either set --prop:/scenery/use-vpb=true on your command-line, or in the Launcher in "Settings" -> "Rendering" (you might need to click on "Show more" on the right side to see the choice for "Scenery version".

WS3.0 can use a lot of memory - significantly more than WS2.0. You can control the memory usage with the following properties:

• /sim/rendering/max-paged-lod controls the minimum number of objects that will be kept in memory. The default setting is 200.
• /sim/rendering/plod-minimum-expiry-time-secs controls how long objects remain loaded for after they are no-longer in view. The default value is 180 (3 minutes).

Reducing these properties will reduce the memory footprint of WS3.0.

If you have lots of spare cores, you can run multiple threads to load scenery by setting /sim/rendering/database-pager/threads to a number greater than 4 on startup. E.g. --prop:/sim/rendering/database-pager/threads=8.

WS 2.0 scenery might still be needed

To have airports displayed plus some of the default scenery objects, you might still want to have the WS 2.0 scenery for the same area installed.

However, if you want updated airports, checkout the global WS3.0 airports above. To avoid collisions you need to not have any WS2.0 airports enabled if you use these.

Using osm2city

WS3.0 has built-in support for OpenStreetMap roads, so you should not have it enabled in rendering settings.

You have 2 options:

• If you have WS2.0 world scenery, then it already contains osm2city buildings etc. You can just use these and live with slight elevation offsets.
• The other option is to use the provided osm2city scenery in the table above instead. If doing so you need to makes sure that WS2.0 osm2city has not been downloaded (or delete the folders manually). E.g. if you are using TerraMaster then you can remove the ticks in Settings for "Buildings", "Pylons" and "Roads".

Using the explicitly provided osm2city scenery gives you trees in gardens/parks and some improvements only available on NEXT.
