Gaia Sky 3.5.6 is out!

2023-10-20 08:49

We are releasing today a new version of Gaia Sky: 3.5.6. This contains some neat new features. These are the most important:

  • add film grain filter (disabled by default).
  • set a maximum age for `.part` download files of 6 hours.
  • improve recursive grid with travelling pulses and a noise mask.
  • add 'animate' setting to recursive grid preferences to toggle animation on and off.
  • add initial notice about Gaia Sky contacting the server to get the dataset updates list.
  • improve shader compilation error handling.
  • enable elevation (height) representation without tessellation in a new 'regular' mode. This is the new default mode, as tessellation is a bit to taxing on old and integrated GPUs.
  • discontinue parallax mapping elevation type; the new vertex displacement type supersedes it.
  • add full support for point lights, and use them for stars.
  • true depth-tested close-by stars, also working with light glow enabled.

Additionally, some bugs have been fixed, most notably some shader crashes on macOS and the usage of predicted positions for tracked objects.

We are releasing today Gaia Sky 3.5.0-RC8, which contains a few neat features, additionally to the usual bug fixes and refactors:


  • Enable holding comma or period to slow down or speed up time. Map time speed up and slow down to d-pad up and down in game controllers.
  • Add trailMinOpacity to trajectories. This raises the opacity of a trail to the given minimum value.
  • Speeding up and slowing down time can be done by pressing and holding '.' and ',' respectively. No more frantically clicking a key. Also, the time warp change is smooth now.
  • Add camera position/orientation named bookmarks, additionally to the already existing object bookmarks. Add bookmarks for many eclipses in the default bookmarks.txt.

Bug Fixes

  • Look-up table paths in procedural generation window.
  • Regression in go-to command with star and particle groups.

Code Refactoring

  • Consolidate shader and resource disposing in post processors.
  • Unify tessellation and regular shader infrastructure.

The OpenXR migration is complete

2023-05-09  15:48

We just fixed the last elusive bug in Gaia Sky VR. The controller interaction with the VR control panel had a problem where the intersection detection was a bit off randomly. With the fix, the interactions with all in-scene VR menus is pixel-perfect. This is the last big issue remaining towards Gaia Sky 3.5.0, so the release is now very close! Here is a video:

Release candidate 2 is out!

2023-05-02  09:27

Gaia Sky 3.5.0-RC2 is now available. It contains some important bug fixes (especially for VR) and a global library update to the most recent versions. As always, this is an RC, so please do not forget to report any bugs you encounter in our bug tracker.

Gaia Sky 3.5.0-RC1 now available!

New features in Gaia Sky 3.5.0

2023-16-04  11:25

The new version of Gaia Sky, 3.5.0, is just around the corner, and it comes with big improvements and exciting new features. In this post, we detail some of the new features in the upcoming Gaia Sky 3.5.0.

  • Migration to OpenXR: we have moved the VR version of Gaia Sky from the old and clunky OpenVR/SteamVR to new standard OpenXR API by the Khronos group, which is supported natively by all the main players in the VR space. Whatever your choice of VR headset, chances are that with this update Gaia Sky VR will work with it.
  • Spherical mirror projection: we add support for the spherical mirror projection for single-projector setups using a mirror. You need to supply your own mesh warp file for it to work. If you don't have your own warp file, you can try with one of the generic one provided here.
  • glTF support: glTF is the new standard format for 3D models and scenes. In this version, we add support for loading glTF models (and also glTF-binary and glTF-embedded) directly into Gaia Sky. This required of some shader tweaking to fully adapt to PBR (physically-based rendering). We now support ambient occlusion and occlusion-metallic-roughness textures in our shaders.
  • New camera key bindings: press and hold Z to speed up the camera motion, use Ctrl-C to toggle cinematic mode, and Ctrl-M to circle between the different camera modes.

Additionally to these new features, the new release comes with many smaller bug fixes, improvements in the JSON data format and new scripting API calls.
