Graphics from 2002 year. Nostalgia.

Someone should make a game inside Celestia. That would be so cool.

Or maybe we need a special game language, like using *.cgame files to build game environments on planets or in space...

I can not speak about games but building cities and making artificial civilizations on exoplanets sounds fun.

Methone:

Edited version:

Methone should be placed horizontally in relation to Saturn.

Thanx, bad model orientation I guess...

look in this thread for my methone texture and a real data methane texture from professional scientists, its way better then what you have, it resembles the photos better
viewtopic.php?f=15&t=21108

here is methone's proper semiaxes



you need no mesh, that semiaxis will do the whole shape job for you because methone is so smooth

with that semiaxis, one bulge should directly face saturn and the other should point away from saturn


if it doen't with the semiaxis i sent you, just

No. Methone's orbit in CO is much more accurate.

okay, what about rotation?

mimas, tethys, and titan from methone

It IS the photo.

it doen't look like it to me, methone is not a object with random purple spots+ methone has some featers that look like cracks

It is the enhanced and color corrected Cassini image of Methone's leading side taken on 20 May 2012.

Yep, the same one. I just enhanced it.

That's all the information I can get from the picture:

i see some very visible albedo features


all that staticness and dotty look that you intergreaded into your texture is just imaging artifact altho i could be wrong...

oh yeah, i don't think methone is purple....

From Wikipedia: Methone has two different sharply defined albedo regions, one distinctly (~13%) darker centered on Methone's leading point.[6] Its brighter area has an albedo of ~0.70.[6] UV and IR spectra gave no indication of a color difference between the two regions, suggesting that a physical rather than compositional difference may be responsible.[6]

This indicates that Methone is composed of icy fluff, material that might be mobile enough to explain the lack of craters.[6][12]

The icy fluff is white or blueish in my opinion.

This is not a ready add-on, so I'm just experimenting.
