I download PSR 1257 system from Rassilon and organize the files like this :
Celestia>Textures>medres>psr1257.jpg files
Celestia>Extras>PSR1257.stc
Celestia>Extras>data>PSR1257.ssc

I tried to change the ssc entrie of PSR 1257 to change HIP 300002 to a pulsar.Today,it is a R star,but I couldn?t do.What is the problem?
The original is like this :

"Pulsar Jet" "PSR1257"
{
Class "comet"
Texture "asteroid.jpg"
Mesh "roughsphere.3ds"
Color [ 0 0 0 ]
BlendTexture true
Radius 0.0001
EllipticalOrbit {
Period 0.001
SemiMajorAxis 0.0001
Eccentricity 0.0
Inclination 45
MeanAnomaly 90
}
Albedo 0.8
}

"Pulsar Jet" "PSR1257"
{
Class "comet"
Texture "asteroid.jpg"
Mesh "roughsphere.3ds"
Color [ 0 0 0 ]
BlendTexture true
Radius 0.0001
EllipticalOrbit {
Period 0.001
SemiMajorAxis 0.0001
Eccentricity 0.0
Inclination 45
MeanAnomaly 270
}
Albedo 0.8
}

And below,are the changes :
#HIP 300002
"Pulsar Jet" "PSR1257" "HIP 300002"
{
Class "pulsar"
Texture "PSR1257b.jpg"
Mesh "pulsar.3ds"
Color [ 0 0 0 ]
BlendTexture true
Radius 0.0001
EllipticalOrbit {
Period 0.001
SemiMajorAxis 0.0001
Eccentricity 0.0
Inclination 45
MeanAnomaly 90
}
Albedo 0.8
}

"Pulsar Jet" "PSR1257" "HIP 300002"
{
Class "pulsar"
Texture "PSR1257.jpg"
Mesh "psr1257.3DS"
Color [ 0 0 0 ]
BlendTexture true
Radius 0.0001
EllipticalOrbit {
Period 0.001
SemiMajorAxis 0.0001

MeanAnomaly 270
}
Albedo 0.8
}

danielj,

There are many things wrong with with what you've written. You really need to take the time to learn what the different declarations mean.

You need to create both STC and SSC files in order to do what you want. You also need to run Celestia v1.3.1 pre4 or later in order to be able to use the necessary STC features -- to give the star an alternate name.

Please reread the documentaion that Thomas Guilpain wrote for STC and SSC files. His Web site is at http://members.fortunecity.com/guilpain/
although it doesn't mention the new STC feature that you need to use.

That starname feature is described on my Web page http://www.lns.cornell.edu/~seb/celestia/addon-intro.html#sidebar

I have downloaded the Celestia 1.3.1 pre 11,and created the Addons folder.But didn?t work.The star is still a red R star.
Look to my ssc.I renamed psr1257.ssc to hip300002.ssc.What I did wrong?

There's no pulsar class

There should be a # before "HIP 300002 " in the first line

It should be in the "extras" folder, not "Addons"

Renaming an ssc file won't actually have any effect on what you're trying to do.

From what I understand, the star itself won't change into a pulsar anyway, the pulsar will be orbiting around the star. (I could be wrong there though)

Well,the pulsar class is Q.
But I did what you tell me,and there isn?t any effect.Nothing is orbiting this star HIP 300002

No no, I meant there's no



Try changing it to planet or moon or asteroid & it might show up.

I have the old version of this add-on installed which has been working fine.

I've just downloaded and installed the new patch from Rass's site and I must admit it does not appear to work for me either. There is a new STC file that looks like it changes the star class from the original version (this seems ok) and the SSC file as shown above by Daniel in his original post. The problem seems to lie in the new SSC, perhaps it needs to be looked at? The lines in the SSC regarding 'class comet', 'texture asteroid' and 'mesh roughsphere' seem mighty dodgy to me!

Here is the old SSC which includes the planets and moons for this pulsar system, and I've mixed this with the new STC and all is working fine;

Now,everything is almost OK.The planets and moon in PSR 1257 appeared.But the star is already a R0 star;i don?t have a pulsar.Is it the problem with Rassilon addon?Where is the old addon?

make sure you have the PSR1257.3ds in the models directory and that the 3ds is in lowercase for both the reference in the ssc file and the file extention itself...Of course if the filename is in all caps the ssc file must reflect the same...

It?s almost OK.Now the pulsar PSR 1257 is inside the R star,or slightly above.When I approach HIP 300002/PSR 1257,the pulsar disappear at some point.In your computer,the pulsar appear alone or inside the original star?Is it possible to fix it?
Could be a problem with Celestia itself?Because the skimo nebula(in Celestia 1.3.0) disappear,too,when I approach it

It is how chris implimented model rendering...He is working on a better perspective rendering method...I think...
