nice, one question, why is the whole moon as dark as the maria we see today, i think it should be lighter, than later in the history, the maria and other dark albedo features form

is this addon close to finished?
you first started teasing it months ago but we never saw a release

Ok can you stop pestering me about this addon? This addon for now is not for the public, even if I finish it.

CM1215, i reprojected and compiled them myself from Cassini images
here is Pan https://cdn.discordapp.com/attachments/753764966863208458/850117017336021022/pan.png

i did not release Telesto's map compilation yet

(i know there may me minor aliment issues, and i do plan to add more available coverage to them)

I made an addon of the TOI-1338 planetary system with the base texture being made from Celestia Origin's saturn.dds and sudarsky-class_2.dds texture (thank Art Blos for the Celestia Origin work) and edited the texture color via paint.net and I made a cloud map for it from scratch using paint.net and gimp.
I posted a screenshot of the planet, but am wondering how I attach the screenshot on here.

Thanks for the advice.
Always something to learn, same goes with finding out what's out there even beyond us.

did you use saturn for the base texture for that?

I said before on one of my previous comments I used the saturn.dds texture and mixed the the sudarsky-class_2.dds texture with it.
Therefore not only can you see the saturn features on the base texture, but also the features on the sudarsky-class_2 texture .
I gave Art Blos a congrats for the Celestia Origin work and textures.
Though the cloud map was all my work made from scratch.
Hope you give me credit for all the work I put into the cloud map.
Those NASA artistic impressions of the planet inspired me to make an addon of it.
NASA also deserves the credits for their effort in the impressions, along with their hard work in finding stuff beyond us.
Therefore I credit NASA for inspiring me to make this.

cloud map looks quite interesting, i am not a fan of the pink color of the artistic impressions because pink is a hard to get naturally due to its complex spectrum

Now the artistic impressions apparently accounted for the fact that the planet orbits 2 stars.
1 F8 (main sequence) star and 1 M (red dwarf) star.
F-stars are whitish and M-stars are reddish.
Yet that's pretty much how the planet looks in the artistic impressions.

i think you should shift the hue towards blue, purple, or cyan, or even green, that will be more realistic for the object (depending on what shade of those colors you use)

Well remember since it's part of a circumbinary star system containing 1 F8 main sequence star (which's white) and 1 red dwarf star, the white and red combo lead to a pink reflection.
Yet the cloud map is technically multicolored from all the certain chemicals interactions of its weather.
Hydrogen, helium, methane and likely water.
In 1 of the artistic impressions, the clouds show pastel patterns along with cyan, green and stuff, though mostly pastel-pink (thanks to the reflection from its 2 stars).
Not to mention planets orbiting 2 or more stars give off a brighter reflection than planets orbiting 1 star (which also corresponds to a higher albedo - which's 0.5 for TOI-1338).

Added after 3 hours 7 minutes:
I haven't found any sources for the positions of the stars in their orbits, but I did make a file of the 2 stars whose positions are based on their epochs (matching the discovery date).

Too bad Celestia Origin has TOI-1338 as a single G-star and the planet as unconfirmed with a radius that's overexaggerated compared to its true radius.
