Update 0.991.50.2155: Ship Material Settings, Catalog Updates, Star Browser Fix

Authors: Jonathan, Brendan
Hey folks~
The August update has passed Beta and is now live! This includes some future-proofing work for system builders and ship modelers, as well as catalog adjustments made from community notes and the addition of the first-of-its-kind exosatellite CD-35 2722 B b.
The full changelog can be found below. You may also learn more about the specifics of the update by clicking here.
Changelog
- M-type brown dwarfs and L-type main sequence stars now have correct labels
- Planetary mass “star” objects with spectral type M and later will now be labeled as planemos
- Spacecraft materials now support gamma adjustment for Diff/Emis maps and green channel inversion for DirectX normal maps. The following parameters have been added for use in .sml files:
- DiffGamma/EmisGamma: values greater than 0 behave as a simple power gamma adjustment, while values below 0 instead use a fixed piecewise sRGB to linear conversion
- DirectXNormMap: a boolean that inverts the green channel if set to “true”
- Fixed a bug where searching for a planet in the Star Browser with a pressure range that included 1.0 atm returned every gas giant in the search radius
- Updated the CD-35 2722 system and added the newly discovered exosatellite CD-35 2722 B b
- Updated Jupiter’s size and shape with the latest Juno data
- Corrected Titan’s mass
- Updated distance to M 99
- Fixed distance, size, and orientation of Ring Nebula
- Added Ring Nebula’s central star as a catalog object
- Fixed distance, size, and orientation of California Nebula
- Reduced luminosity of Pleiades Nebula for increased realism
- Updated distance to Puppis A
- Added newly published properties for The Garnet Star
- Corrected orbital parameters of Mu Ara’s planets
- Removed liquid ocean from Wolf 1061 c
- Updated Gliese 777 system (removed extra planets, added missing d planet, updated properties for b and c planets)
- Updated the exoplanet catalogs with 27 new host stars, 30 new planets, and five new brown dwarf candidates
- Added 12 new binary asteroid systems, updated some binary system names
- Added newly assigned name to 1999 JB80: Karolinadziadura
