Re: TRAPPIST-1 system: 7 Earth-sized planets

You are right, but at least it "works" in Celestia 1.6...a step in the right direction. :)

With planets with 1 km radius. :cry:

Re: TRAPPIST-1 system: 7 Earth-sized planets

I have a version of the TRAPPIST-1 system on Celestia, but with only 3 planets. In a new ssc file the 3 habitable planets should have Earth-like atmospheres...I'm very curious to see the faint star from the surface of the planets... The "old" TRAPPIST-1 ssc file: "TRAPPIST-1 b" &...

Look at the bright side of it. The Celestia Developement Team now will have the time to enable Celestia 2.0 to handle the one billion star data...

RAM usage indicator and RAM "loading" sign on the Celestia screen?

In my experience Celestia often crashes between 1500MB and 2000MB RAM usage on Windows. It would be nice to have a "Loading..." sign on the screen during the RAM loading, because the screen often freezes during loading large textures or models. Also the actual RAM usage should be on the sc...

Whoa, the patch is good, Celestia crashed approximately at 2000MB RAM, but it went to 2100MB at one point before the crash. By the way, is it possible to have a "Loading..." sign on the screen during the RAM loading? It would be nice... Also RAM usage should be on the screen too, it would ...

Re: Distance to object

selden, thanks for your reply.

Intel Core i5 8GB RAM + AMD Radeon HD 7700 8GB.

Paging file is 3456 MB.

Celestia is crashing for example at 1437MB RAM. RAM data is building very slowly (with maybe 30s-1 minute "screen freezes"), but CPU usage is never above 50%.

Re: Distance to object

Png texture produces the same problem. One 8k planet means that I load 8k 20mb dds surface texture + 8k specular texture + 8k 40mb png bump map texture. After 5-6 planets (or maybe more) Celestia first cannot load some part of the new surface texture of a new planet and after that it crashes... &quo...

Re: Distance to object

I don't think it is a Windows 10 or graphic card/driver problem, because no other graphic 3d software produced this kind of problem, including Space Engine which uses 128k textures... I can use Gimp to edit 32k texture files in the GB data range with no crashes. It can only be the problem of the Win...

Re: Distance to object

KInda offtopic (sorry): 32 bit Celestia under Windows 10 64 bit is always crashing after loading too many textures. This is annoying and severely limiting the use of the program. On the other hand the new GAIA star data would need approximately 20GB star.dat to work, so in my opinion RAM usage and 6...

Re: Cloud bump maps and cloud colouring feature?

Nice work, they seem quite real despite of the low resolution! Celestia has another issue, which can be a more serious problem. When using 32k multi-layered cloud textures you cannot move the textures, so they must be motionless. One-layered cloud textures on the other hand can't really have higher ...
