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).

Example:

Title: HD 189733 b Description: Three textures for the exoplanet HD 189733 b, including a true-color fictional texture and two temperature maps.

Good, let's do that. Maybe you can get a template ready for submissions? For every add-on there should be title, description, authors, release date. Optionally, localized title/description and image. I'll change the link to redirect to this issue.

[levinli303]

@DaveBowman2001 great, I've made them available now.

there is issue with the ISS add-on on iOS, though. It is very likely that the naming in the .ssc and the actual file naming are not matched, since on iOS the filesystem is case sensitive. The Mars Pathfinder add-on has the same problem but it was easier to fix I fixed it for you.

[DaveBowman2001]

That's odd....not even a single Soyuz/Progress appeared....I'll look into it for iOS releases. Thanks!

@DaveBowman2001 they should all be live on mobile celestia now, thanks!

[DaveBowman2001]

Thanks @levinli303! But the Cassini addon I posted is broken. This was reported on the Forum I provided an update fixing this issue on the original post. Thanks again!

[levinli303]

@DaveBowman2001 I think have updated the new file, can you try uninstalling and installing back again? Also please check the top of the thread. I made some changes: Demo Object Name/What makes a good compatible add-on

[DaveBowman2001]

Hello @levinli303, unfortunately the current download link still uses the older problematic SSC file (the screenshot below was taken moments after downloading it again): The old SSC file was dated 2021-Dec-26, 11:50 (UTC+8), while the supposed new one was finished 12 hours later, 2021-Dec-26, 23:49 (UTC+8)

No matter, this is the new zip re-uploaded to my drive....hopefully this works: Cassini-Huygens (update).zip

My apologies for the troubles caused by this mod

EDIT: I can confirm the download link for Cassini-Huygens is fixed now! Thank you very much!

Abell 6 is a faint planetary nebula, and is often photographed alongside the visually nearby planetary nebula Heckathorn-Fesen-Gull 1 (HFG 1), which is not included here. The nebula is poorly studied, so the actual 3D structure is not known; my model is a best guess that appears correct from Earth's viewpoint while appearing realistic from other directions.

Title: Abell 7 Description: This add-on adds a realistic, fully 3D model of the planetary nebula Abell 7. The model is based on an photograph by Don Goldman. The 3D model appears roughly correct from Earth's view, (in true color, but ignoring the fact that the surface brightness is too low for it to be actually visible to the naked eye), but the overall 3D structure is a best guess such that it appears plausible from other viewpoints.
