slashi,
The dds files are not models, they're just graphic files in a special compressed format (DXT1c) and are exactly the same textures as the jpg's. In order to use them you've got to edit or create a custom ssc file wich makes reference to the texture you want to use. Let's see how it works:
Create a text file called test.ssc and save it with ssc extension in the extras subdirectory, and copy and paste this code:
Code: Select all
"Brown Dwarf Test" "Vega"
{
Texture "browndwarf.jpg"
NightTexture "browndwarfnight.jpg"
Color [ 5 1 0.9 ]
Radius 70000
Atmosphere {
Height 900
Lower [ 1 0.3 0.1 ]
Upper [ 1 0.3 0.1 ]
Sky [ 1 0.3 0.1 ]
}
EllipticalOrbit {
Period 200
SemiMajorAxis 70
Eccentricity 0.048
Inclination 1.3
MeanAnomaly 0
}
RotationPeriod 10
Albedo 0.40
}
Save it, start Celestia and go to Vega, then right click on the star and select "Satellites" and then "Brown Dwarf Test" you'll see this:
This will place an imaginary (not real!) brown dwarf orbiting Vega. A file that specially points to brown dwarves is extrasolar.ssc (makes reference to extrasolar planets orbiting stars, and also brown dwarves, i.e "70 Vir b")
