Wrap lighting can be used to fix an error with cloud rendering around the terminator of an object. Here is what that looks like with Titan, and a real photo of Titan for comparison.

Improvements have been implemented. In the third image, Titan's atmosphere has a much softer edge, this is achieved by simply lowering the AtmosphereExtinctionThreshold in the source code.

By using the Chapman function, scattering can be made more realistic, especially for tall atmospheres. Here's what that looks like with Titan. Not final, subject to change.

Earth's atmosphere has been overhauled using data from various studies, and true colour images as a reference. The same has also been done for Venus, Mars, Titan and Pluto.

Unfortunately the current scatterer creates some inaccuracies which can't be fixed without rewriting it, which would push the final release of version 1.7.0 even further back.

Now that sRGB rendering has been added, we can revert the Earth's atmosphere parameters back to the ones used before 1.7.0, making it more accurate to true colour photos of Earth. Views from the surface also look better.

Designed and rendered in Blender updated wordmark for @CelestiaProj
After some modifications, it will be used for the new splash screen that the community is currently working on

[Celestia @CelestiaProj]

This is part of a bigger branding overhaul I'm working on, mostly for the Steam store page and library assets. Includes a new logo with this lovely (and free!) font called Zen Antique! Really happy with this font choice

[Celestia @CelestiaProj]

New splash screen? 👀

No less than 60 million stars in one image.

It's possible thanks to the @ESA_Euclid mission.

For just one day, Euclid turned its gaze to the crowded heart of the Milky Way and captured the largest, most detailed photo ever taken of our galaxy's centre in visible light.
