Check before uploading an add-on

Your add-on will be running on Android/iOS/macOS/Windows, to enable maximum compatibility, please ensure that

1. files names referenced in models, ssc, dsc files, etc are exactly the same as the actual file names (some file systems are case sensitive. For example if in your .ssc there is Mesh "Progress.cmod", then the file name should be exactly Progress.cmod not progress.cmod).
2. Textures should have width/height of power of 2 (for example: 1024 512, a texture of 1000 500 will not work on many mobile devices).
3. If your add-on requires specific Celestia versions, please mention in the description. Please also ensure that your add-on should not crash running on other versions.
4. If you are updating an existing add-on, note that existing users will not see an update button, so it might be a good idea to include version history in the description.
5. Please try to use smaller files for image/thumbnail/other metadata. For example, use JPG if alpha value is not needed.

Example:

Title: Explorer 1 to 5 Description: The first generation satellites of the still-active Explorers program were among the very first spacecraft successfully launched into orbit by the United States. Although unable to beat Sputnik on being the first artificial object in space, the Explorers (particularly Explorer 1) discovered the existence of a region of charged particles around the Earth's magnetosphere called the Van Allen radiation belts. Five satellites were launched in 1958, only three were successful (1, 3 and 4). All of them operated for four months each, but stayed derelict in orbit for many years until 1970 Proposed category: Spacecraft Demo Object Name: N/A Author(s): Jack Higgins, DaveBowman2001 Release date: 2022-Feb-24 Link to download: Explorer 1 to 5.zip Image:

Title: Antares Description: Antares is a bright red supergiant star about 610.6 light-years away in the constellation Scorpius. It is the 15th-brightest star in the night sky, and like all variable stars, its apparent magnitude changes over time. It is likely to explode into a supernova in the next 10,000 years Proposed category: Stars Demo Object Name: Antares Author(s): trappistplanets Release date: 2021-Mar-19 Link to download: Antares.zip Image:

Title: Luna-3 Description: Luna-3 was a soviet space probe with the objective of carrying out a flyby of the Moon. Launched on October 3, 1959, it performed a flyby at a distance 6,200 km of from the Moon on October 6, 1959 and made the first images of the far side of the Moon that is not visible from Earth. After the lunar flyby, Luna-3's fate is uncertain, but it is believed to have impacted Earth's atmosphere in the year 1960.

Update to D/1993 F2 (Shoemaker-Levy 9) addon

Description: Comet Shoemaker-Levy 9 is a comet that broke into at least 21 fragments due to its close encounter with Jupiter in 1992. It has garnered the interest of many astronomers as it was predicted to collide with Jupiter on July 1994. It was speculated that it was a short-period comet that was captured by Jupiter's gravity sometime in the 1970s, and measured about 5 km in diameter before its 1992 break-up. The collision events contributed greatly to the knowledge that Jupiter's strong gravitational influence decreases the chances of asteroid/comet impacts to occur particularly on Earth
