Development news

Update: 2020.1.1 released on May 10

2020.1.1 has been released. See the changelog for what's new.

2020.1.x is a preview release including new features that that will be in the next stable release, but receive less testing and some aircraft maybe incompatible.

WiP Compositor enabled in 2020.1

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 Windows installer will currently place a link for the compositor under the Flightgear 2020.1.1 folder in Windows start-menu. This 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 youngest country with overlays as well as several volcanoes including Eyjafjallajökull which caused severe disruption to aviation in 2010.

Compositor binary is now bundled in Windows nightlies

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

Nighties will now build towards the stable release planned for sometime towards the end of the year, 2020.2.

(Out-of-date) 2020.1 release preparations

The release candidate for the 2020.1 release has been tagged. Release candidate builds should become available for testing at download.flightgear.org sometime in the future.

Nightlies, available now at download.flightgear.org, will build towards the release after 2020.1, which is planned to be sometime towards the end of the year.

Compositor video

Tim/MrChillstorm has made a video showing progress so far on porting ALS effects and shaders to the ALS pipeline of the Compositor. 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.

Work in progress state of the Compositor ALS pipeline. The shadows on the aircraft, and aircraft shadows near the ground at 11:47 are done at by the compositor. Not all effects & shaders at all quality settings have been ported yet, causing somethings to not render. If you are testing the compositor builds you can try to find a combination of shader quality settings for the aircraft and terrain you are in.

New software tools and projects

Red Griffin ATC release

Red Griffin ATC is a speaking Air Traffic Controller addon for FlightGear using NASAL. It uses existing Text To Speech (TTS) functionality to produce speech. Newer versions of Flightgear (later than 2018.3) support addon installation from the launcher (try nightlies if 2019.1 doesn't have addon support).

The addon is being developed by Red Griffin (Antonello Biancalana). It's a candidate for eventual integration as part of the base install of FlightGear.

See the article for more demonstration videos.

See the Red Griffin ATC - Speaking ATC addon for Flightgear topic on the forum This is a link to the FlightGear forum. for feedback and download.

Cargo Towing Addon release

The Cargo Towing Addon adds cargo towing capability to any aircraft with some XML editing if load points are not present.

The addon is developed by wlbragg (Wayne Bragg) and uses the soft-body rope physics simulation created by Thorsten Renk.

Help wanted

Post LTS work

After the 2020.2 release, some work lies ahead to improve the LTS - any help would be greatly appreciated.

This may for example include:

Please get in touch via the developers mailing list to learn more. See Post FlightGear 2020.2 LTS changes for more details.

World Scenery 3.0

The FlightGear project is in the process of exploring how Virtual Planet Builder can be adopted. For details, see: World Scenery 3.0 roadmap

Aerial (drone) photos for Terrain textures

Wanted: good top-down aerial photos to create textures from to use with the procedural Regional Texturing system. Drones This is a link to a Wikipedia article with cameras are ideal. People with access to drones are in a good position to take high-quality photographs.

A particular need as of 2020 is photos of agriculture (farm lands) from different parts of the world.

Good GPLv2 compatible photos suitable for textures are hard to find, and an easy way is for people to take photos of their region. Flightgear's procedural systems can do a lot with less art content, so photo contributions can strongly improve visuals.

See: How to: take photos of terrain for textures. For examples of final textures: see /data/Textures/Terrain. e.g. UK countryside.

You can get in touch via the Scenery forum or the flightgear-devel mailing list

Photos of trees for textures

Wanted: good quality photos of different trees and vegetation from various parts of the world. Flightgear's vegetation system can handle multiple layers of trees and bushes.

Strong shadows should be avoided. Each tree should be against a background of a different colour: sky (preferably) , clouds , or buildings. This allows the tree to be separated from the background in a photo-editor like GIMP.

See: How to: take photos of vegetation. For examples of final textures: see /data/Textures/Trees. e.g. Coniferous.

You can get in touch via the Scenery forum or the flightgear-devel mailing list.

Submissions of default settings for GPUs

Wanted: Reasonable default scenery and graphics settings for different graphics cards, to use with the new GPU profile system. See this forum thread to submit defaults for your GPU.

Submissions of labels for craft

Wanted: Submissions of labels (tags) giving a rough description of aircraft - Metadata tags. A quick read of a craft's Wikipedia page will normally be enough to set labels. This info will be searchable from the launcher GUI. For example, filtering craft by propulsion like single-propeller or 4-engine jet craft, or by a manufacturer like Airbus or Grumman, or by speed like supersonic craft, or craft by era like WW2. A list of tags is here - more can be added if needed. To add tags to craft yourself, the tags are stored in the set-xml file.

A list of FGAddon craft needing tags is here. See this forum thread to submit tags. The flightgear-devel mailing list or the craft's maintainer can also be contacted.

Windows Package Maintainer

The core team needs help from Windows users able to maintain a good working Window build. This process already exists to support our Nightly and Release builds, but we are seeking additional help to keep it in good working order. The ability to compile FG from source and some Windows batch scripting is a required skill. If you are willing and able to take up this role, please reach out to James Turner (mailing list), or get in touch via the forum [1]

Videos

Tim/MrChillstorm's 4k 60FPS WiP development videos

(mostly at high-ish or max settings)

At high graphics settings/resolutions the bottleneck is the almost always the GPU. A 4k (3,840 x 2160) resolution is the equivalent of trying to run four standard 1080p (1920x 1080) monitors with one GPU. Recording videos also slows down performance. The reason why around 60 FPS at 4k resolution (on a top end GPU from the last ~4 years) is even possible is the surgical way ALS creates custom strategies for different cases based on the needs of a flightsim, and the way ALS prioritises GPU cost of features based on overall visual impact, spending a greater proportion of GPU time for features that have more impact generally.

These videos are mostly in WiP scenery missing something things, and don't necessarily have the most busy weather settings (unlike this 4k/60 FPS video showing FPS is mostly unaffected), but the general observation holds.

Australian Scenery Project Queensland release

Merspieler has released a test build of the state of Queensland (QLD).

The Australian Scenery Project is coordinated through gitlab.

See the forum thread for feedback and download (3.5 GB).

Virginia, Maryland, Delaware, and DC custom scenery release (USA)

Montagdude has released custom scenery for the states of Virginia, Maryland, Delaware, and Washington DC in the USA. The scenery includes terrain elevation, landcover, rivers and waterbodies, some custom regional definitions and some textures, as well as OSM2City output. This custom scenery is a significant improvement in resolution as the USA does not have the high-res CORINE data that Europe does.

See the article on Using QGIS to process NLCD data by Montagdude for a tutorial on how to use new data sources to create US scenery that is on par with the existing European scenery.
