Well, if any, the devs might not be focusing on that right now. Hopefully they will soon. If I remember, they are focusing on making a proper database for an Universal Object Identifier for Celestia right now. In short, they are making a catalog that is exclusive to Celestia and encompasses all objects in Celestia regardless of whatever real-life astronomical catalog they belong to. You can read about that in this thread: viewtopic.php?f=4&t=19521

I have many cities on the surface of planets and moons, They just disappeared, both in the win and the qt version. :fie:

The win version has many other problems but the qt version works nicely - apart from this problem...

Do the cities have model files of their own or are they just location identifiers?

They have huge cmod files, hundreds of MB.

But this simple, very small cone won't work either.

Should I write to Onetwothree?

Absolutely. He's one of the devs, and based on this thread's beginning, the current principal developer of Celestia 1.7.0 right now

OK, thanks.

The problem is not the location, but the invisible cmod file. You can see the location, the right radius, but it is invisible...

Yup. It's made evident by "one1" appearing invisible

Just a quick note.

Commit 5471, current as of me writing this, lacks a ceres texture.
I copied the lores/medres testures from 5445, and it worked fine.
Someone might want to audit the base data for self consistency.

We aware of this. Will fix it with better version when it's ready.

I have fixed Celestia to show them. But they are shown only if their parent body is visible. Is such behaviour is ok for everybody?

Well, it's alright. The objects look better with their parent body present anyway

onetwothree,
I have fixed Celestia to show them. But they are shown only if their parent body is visible. Is such behaviour is ok for everybody?

Thank you very much! :clap:

Visible parent bodies are OK, but I use a lot of invisible barycenters to build multiple star systems.

I hope it cannot be a problem!

Also I would like to point out, that a lot of my planets are in fact moons orbiting a gas giant...

The cities are on the moons...

Where can we download a windows version to test?

Nice work by the way!

Added after 4 minutes 49 seconds:
Also we should test Dyson-spheres with inner surfaces (inner oceans).

I built some megastructures around stars too, literally on their surface.

This change affects only surface features. Nothing else.

It's not built yet, I want to wait a bit to gather feedback, maybe somebody unhappy with such change.

onetwothree, Here is another bug.

Maybe it is the same problem.

Large cmod objects around stars (megastructures) are also invisible.

Here is an ssc file (problem2). If you search for one2 in the Solar System, you will find it, but the cmod file is invisible - again.

This regression is fixed as well. But Celestia has another bug with such objects - you have your dyson sphere around the Sun, you select the Sun and go to it and you don't see it. 1.6.1 has this bug too.

On the other hand - maybe your one2.cmod just have an outer sphere?

Nice! :clap:

Yes, you need another sphere to have an inner surface.

Try this Dyson-sphere from Motherload, it has inner surface:

A new win32/64 snapshots are published to https://dl.bintray.com/celestia/celestia-builds/ (only main binaries are updated as data and tools saw no changes since the previous release).

Not so many changes comparing to other releases:
* Build instructions updated (guys I really urge you to build yourself :))
* Regression causing invisibility of "diffuse" and "surface feature" objects was fixed
* Planet rings if present are rendered much faster

I tried the new commit and there still seems to be a problem. I tried john71's problem file for surface features.

You have a cone on the Earth. John's test modes are simple, without colors or anything else. But they are visible.
