Comet Wild 2 not shown like a comet in Celestia

[danielj]

Comet P/Wild2 is defined in Comets.ssc,but in Celestia it don?t show ant tail.And when you use the label comets,it doesn?t appear,but when you label asteroids,it shows off.
Other thing,maybe it?s possible to develop a texture for comet Wild 2.If only one henisphere is know,do like Saturn?s moons where the not known areas are bland or repeated.It would be much better that the usual Comet.jpg.
I don?t know how to work in textures.I only know to resize it,using Paint.I was in trouble,even using anim8r,because the tutorias are very difficult.
Anyway,I?m not in a hurry and it?s only a sugestion

Hello Daniel

Do you have this as the second line in your code ?

Code: Select all

   Class    "comet"

Should look somthing like this

Code: Select all

"81P Wild 2" "Sol"
{
   Class    "comet"
   Mesh     "comet.cms"
   Texture  "comet.dds"
   Radius    2.0

   EllipticalOrbit
   {
   Period              6.4034958
   PericenterDistance  1.5903645
   Eccentricity        0.5388043
   Inclination         3.2402320
   AscendingNode     136.1418283
   ArgOfPericenter    41.7515936
   MeanAnomaly         0.0
   Epoch         2452908.440060
   }

        Albedo 0.2
}

I don't think that anim8or is the best program to use for making asteroid / moon etc models in Celestia. It tends to produce a blocky, shiny model with a pronounced seam. I don't know what Jestr has been using for his Minormoons? All I know is that they look fine.

You have a comet dds texture!? It isn't in the standard 1.3.1 textures is it? 'Cos I went and replaced them immediately without looking

Well,I tried,but it appears that we should have a better defined Comets.ssc file.I first change the Wild 2 to the class "comet".Ok,it worked.But then I renamed the texture to "Comet.jpg" and in this case,didn?t work.Then I cut Wild 2 from Comets.ssc and paste in solarsys.ssc and it remain with the texture asteroid.jpg.I could change Ikeya Zhang,Halley and Borrely but not Wild 2.It seem that,somehow,it is tied to the file "Comets.ssc" and my procedure didn?t do anything(except changing its class).Other thing: Wild 2?s nucleus is out the coma,like being floating in the sky.
I would like to know,either,where did you find a Comet.dds texture
Look to my changes and see if you can help me :

And Borrely in comparison:
