Development news

2020.1.2 Bugfix released on May 26

2020.1.2 has been released. See changelog.

2020.1.2 also allows selecting the two Work-In-Progress Compositor pipelines from the in-sim launcher. In Windows there is a Compositor shortcut under the Flightgear 2020.1 folder in the startmenu.

To choose pipelines go to Launcher > Settings > Rendering > Renderer and select from the drop down list.

  • Choose Atmospheric Light Scattering to select the new ALS pipeline. This is the pipeline most people should use, and should be attempted first. ALS with shader quality settings turned down can be faster than the low-spec pipeline. Read sections below for how to turn on shadows.
  • Choose Low spec to select the new low-spec pipeline. This replaces the old default renderer. It is for very old hardware. It also serves as a fallback for newer systems that have compatibility problems for whatever reasons.

Note: The 3 commit histories are viewable on sourceforge for the 2020.1.x branch - note 2020.1.2 split points: Flightgear , Simgear, and FGData.

2020.1 released on May 10

2020.1.1 was released. See the changelog for what's new.

2020.1.x is a preview release including new features and infrastructure changes that that will be in the next long term stable release (LTS), but receive less testing and some aircraft maybe incompatible. Please test.

Aircraft developers, as always, if you notice a system that is meant to be working, is buggy or broken in a new release, please report it as a bug instead of working around it. The same input aircraft data working differently is a classic way to detect a problematic change in Flightgear. This applies to performance degradations too. The Sourceforge Tickets or the devel mailing list are options for reporting. The sooner problems are reported the quicker (possibly serious) underlying causes can be identified and fixed. These underlying causes may affect other areas where the symptoms are harder to pick up. One of the strengths of opensource 'release early, release often', needs reporting to work. As a general point, it is less work to make any structural changes needed as a result of problems identified early, compared to structural changes after possibly building on those foundations.

WiP Compositor enabled in 2020.1.x

The Work-In-Progress state of the Compositor is bundled as an additional binary for testing on a wide range of systems. Read sections below for more info and how to turn on shadow mapping in the ALS pipeline.

The ALS pipeline has new shadows for objects like buildings via shadow mapping. There are default shadow maps for cockpits that are slightly slower and lower quality than the ALS version. There are similarly slower shadows for aircraft, that do not have the faster versions implemented.

For now you can control shadows and map quality by the following command-line options:

  • --prop:bool:/sim/rendering/als/shadows/enabled=true
  • --prop:int:/sim/rendering/als/shadows/sun-atlas-size=2048. Higher map size (sun-atlas-size) means crisper, slower, shadows. Power of 2 values to try: 2048, 4096, 8192.

These options can be also be set in the settings page > additional settings section of the in-sim launcher

The Windows installer will currently place a link for the compositor under the Flightgear 2020.1 folder in Windows start-menu.

Keflavik airport using the Compositor in 2012.1.1 by MrChillstorm. Note shadows by objects ground. Some shader settings may not be maxed as they are not ported. Overlays need 2020.1.2 to work. OSM2City for Iceland is not installed.
Compositor shadows in multiplayer by Wlbragg. The helicopter is a work-in-progress branch of the Aircrane with a lot of improvements that is only compatible with the Compositor.
2020.1.1: Windows Startmenu Compositor link

If you are still using 2020.1.1, the windows startmenu link will activate the low-spec pipleline that replaces the old default renderer. To specify the pipeline, for example to get the ALS pipeline, use the following command-line options:

  • --compositor=Compositor/ALS. Specify ALS pipeline.
  • --compositor=Compositor/low-spec. Specify low-spec pipeline.

These command-line options can be set in the settings page > additional settings section of the in-sim launcher. In Windows, they can also be set in the shortcut properties > target accessible by right-clicking the shortcut - you can copy/paste an existing shortcut.

Keflavík is the featured airport for 2020.x

Keflavík International Airport, ICAO code: BIKF, is the largest airport in Iceland, located in Keflavík near the capital Reykjavík in the south of the island. The release includes the terrain for Iceland.

Vanosten has released OSM2City output for Iceland in the form of buildings, roads, pylons, etc. This can be downloaded and installed. There are two types of Buildings included with separate folders that can be renamed to select building type:

  • 2020.x and later: rename the "Buildings_list" folder to "Buildings". This uses the new, fast, buildings.
  • 2019.1 and earlier: rename the "Buldings_mesh" folder to "Buildings". This uses the older, slow, buildings.

Iceland is one of the more developed regions of Flightgear currently, and features detailed depiction of the striking volcanic terrain of the world's geologically youngest country with overlays as well as several volcanoes including Eyjafjallajökull which caused severe disruption to aviation in 2010.

Iceland, at high settings in Flightgear with overlays on and transparency AA set high. Try overlays in Iceland - the lack of vegetation means there is spare performance in somewhat recent systems with discrete GPUs (laptops may only have integrated GPUs, or much slower mobile GPU variants in GPU series before GTX 10xx)

Compositor binary is now bundled in Windows nightlies

The compositor build is available as a second binary: bin/fgfs-compositor.exe.

As of June 1st, several more effects have been ported to the ALS pipeline. Those using nightlies can try experimenting with overlays which are fixed.

The road ahead: 2020.2 LTS Plans

The next long term stable release is 2020.2.x LTS. This replaces 2018.3.x LTS.

Long term releases (LTS) are supported over 1 to 2+ years. Bugfixes are ported back to stable releases. The last number in the version number is incremented for each bugfix release. For example: 1st release: 2020.1.1, 2nd (bugfix) release: 2020.1.2.

The plan is for the next branch and nightlies to build towards 2020.2 by polishing and stabilising. 2020.2 will be split off soon, tentatively around 'mid-june'. 2020.2.1 release candidates should become available sometime after that for extensive testing. The 2020.2 release is planned to be towards the end of the year, tentatively around September. As always dates can change due to plans needing changing for various reasons, or availability of people.

See the mailing list for details.

Compositor is planned to be the default rendering framework

2020.2 LTS will switch to the Compositor as the main rendering framework. The Compositor framework exposes a lot of powerful abilities for pipelines to use as Flightgear evolves in years going forward.

  • The ALS pipeline will be a port of the current version of ALS. It will have a few extra things added. Future versions beyond 2020.2 will add more features.
    • It's planned that 2020.2 will add shadow maps. These shadows maps are for certain cases where there were no shadows before like with buildings, or for use in craft where higher quality ALS shadows are not implemented yet.
    • It's planned that 2020.2 will also add clustered lights - these are not fully implemented yet so it's possible plans may change. It's planned that all lights will use the a similar input format as Rembrandt, including craft landing lights/spotlights/etc currently in ALS format.
  • The low-spec pipeline will replace the default pipeline.
  • The current rendering framework is still planned to be included in 2020.2 as a fallback. 2020.2 LTS should be the last version to support the current rendering framework and renderers.

2020.2 Compositor: Aircraft need to be checked and ported (e.g. lights)
