The Aurora system will be a big planetary system which depicts a (rather long!) list of planetary apocalypses and extreme scenarios. The project is in development and I won't tell you too much as most of the system should be a surprise when released. The final release date has not been defined yet, ...

Thx! I have converted it with Orbiter-Blender (An addon for Blender). The updated addon is available in the main post.

IM-1 (other names: Intuitive Machines 1, TO2-IM, Odysseus) is a moon lander that launched on 15th February 2024, at 06:05 UTC and landed on 22nd February 2024, at 23:24 UTC near the Moon's south pole . During landing it tipped over, but it is still intact. ( Read More ) Intuitive_Machines’_Nova-C_lu...

There should be an option to not check "multi-line object definitions/strings". Use the 1.2 version which is the same as v1.3, but without the multi-line check. v1.4 additionally supports .xyz(v) files, but it won't block your checks since there are no strings in .xyz(v) files anyway. Re-...

This addon adds a Christmas tree to Celestia because in my country and some others Christmas is celebrated on 24/25 December and the days after that (the link is mainly for people who don't know what Christmas is, e.g. because it's not celebrated in their country). If you don't want a "Christma...

Oh ok, but it still looks funny on normal monitors.

So, because I was curios on what would happen when I set the options in Celestia 1.7.0 sRGB's celestia.cfg file like the ones below: Screenshot (77180).png ..., I found out that this makes Celestia look really weird: Screenshot (77178).png Screenshot (77177).png Screenshot (77174).png Everything get...

This addon adds my Jupiter texture (click the link for more information about the texture) as an AltSurface to Celestia. Right-click Jupiter, select "Alternate surfaces" and choose "Jupiter (by EarthMoon)" from it.

So, because I was bored, I have created a 2k texture for Jupiter, based on an image by the Cassini-Huygens mission: Jupiter_by_Cassini-Huygens.jpg This is the texture (created with GIMP and a few edits with MS Paint ): JupiterEarthMoon.png Because the image only shows one side of Jupiter and it is a...

See the first post.

ps : 1.2 version is not published here ! As the first post says: "If you need an older version than the latest one, comment below or PM me.". I only upload the latest version and remove all older ones (except the celcheck_test1.exe because of your ongoing problems/errors, I will delete th...

More than a year ago, I have published some planetary textures ( CelTextures Vol 1.0 ). Now I have created another bunch of (really better) 2k textures: CelTextures_Vol_2.0-preview.png *.jpg: Default/Albedo/Diffuse Textures *_e.jpg: Emsisive/Night maps *_s.jpg: Specular maps *_n.jpg: Normal maps The...

You have two options to edit the texture of the .cmod (I recommend the easier (2nd) one): The harder way: Open the file with a text editor and edit the material's texture0 properties (or add them if required), see https://en.wikibooks.org/wiki/Celestia/3D_Models/CMOD_File#Example_ASCII_CMOD_File (re...

A solar eclipse in Celestia: eclipse-raw.png Edited to make atmosphere/sky darker as Celestia does not calculate the effects of this kind of shadows in atmospheres: eclipse-edited.png Proof that the sun is really in Celestia and not just an overlayed eclipse image: eclipse-sun.png Maybe I will creat...

You could make a version with double line control and another without! The new 1.3 version already has this double line thing (strings [data enclosed in " "] can be even multi-line (2, 3, 4, ...), not only double line; parameters can also be multi-line: Name on one line, value on a later ...

A hill sphere is "the region around a planetary body where its own gravity (compared to that of the Sun or other nearby bodies) is the dominant force in attracting satellites, both natural and artificial." ( Wikipedia ). The radii have been calculated using a formula which can be found in ...

See first post.

Your program does not recognize certain characters in the file name, for example "°", although celesia accepts them. "Celesia accepts them" yes. But what about the file system the addons gets installed on? Not all file systems support all characters, so I will let ° disallowed, ...
