Clouds textures for Mars

[danielj]

I put the texture "mars-clouds.png" and followed the instructions.But I didn?t notice any differences.How can I know that my Mars has clouds?Is it subtle?If so,I would like some texture which this clouds are not so subtle

[Darkmiss]

as far as i know, there isn't any mars cloud maps that are that subtle that you just can tsee them.

also make sure you have clouds turned on with the "I" key

other than that.....
you need to add some extra code to the end of the atmosphere section of Mars, in the solarsys.ssc

Check to see if you have the "cloudmap" section in your mars code ?

Code: Select all

   Atmosphere {
      Height 40
      Lower [ 0.8 0.6 0.6 ]
      Upper [ 0.7 0.3 0.3 ]
      Sky   [ 0.83 0.75 0.65 ]
      Sunset [ 0.7 0.7 0.8 ]
      CloudHeight 10
      CloudSpeed 500
      CloudMap "Mars-clouds.dds"

also where I have "mars-clouds.dds"
make sure this matches the name of the cloud file that you downloaded.

EG: mars-clouds.png, or marsclouds.jpg ?

this is what i use

Code: Select all

"Mars" "Sol"
{
   
    # Texture "BlueMars.png"
    # Texture "Mars.png"
    Texture "mars.dds"
   # BumpMap "MarsBumpT1.png"
    # BumpHeight 6.0
    NormalMap "MarsNormal.png"
   Color [ 0.20 0.15 0.15]
   SpecularColor [ 0.15 0.10 0.05 ]
   SpecularPower 8.0
   HazeColor [ 0.1 0.1 0.15 ]
   HazeDensity 0.03
   Radius 3394
    Oblateness 0.006

   Atmosphere {
      Height 30
      Lower [ 0.8 0.6 0.6 ]
      Upper [ 0.7 0.3 0.3 ]
      Sky [ 0.83 0.75 0.65 ]
      CloudHeight 80
      CloudSpeed 200
       # CloudMap "MarsClouds.dds"
       CloudMap "MarsClouds.png"
   }

   CustomOrbit "vsop87-mars"
   EllipticalOrbit
   {
   Period            1.8809
   SemiMajorAxis     1.5237
   Eccentricity      0.0934
   Inclination       1.8506
   AscendingNode     49.479
   LongOfPericenter 336.041
        MeanLongitude    355.453
   }

   RotationPeriod    24.622962
   Obliquity         26.72
   EquatorAscendingNode 82.91
   RotationOffset    136.005

   Albedo            0.150
}

also for some strang reason if the dds texture was made using Microsoft's dxt tool ( in the diect x 9 sdk ) celestia will crash but there is no problem with the tool from direct x 7 or 8

ooops i was playing with my cloud settings a few days ago, and forgot to put things back as they were.

cheers John, my speed and height settings was way wrong.


No sunset settings John....?

[John Van Vliet]

no sunset yet on mars but earth looks leally cool when you are less than .5 km from the ground .

my mars cloud speed and height are for looks and are not 100% correct

I have downloaded the new 16k Mars from the forum, and it is awesome. However, none of the cloud maps I have match the position of the new texture. The clouds are all offset from Olympus mons and the other volcanoes.

Does anyone have a cloudmap that matches the orientation of the new 16k Mars? If so, could you post a link to it, or tell me where to get it please?

Thanks

I could not see Mars clouds in an alternate texture, but I solved it by adding a "CloudMap ..." entry for Mars in the celestia/data/solarsys.ssc file.
