A alternate surface problem

Post #1by mspo100 » 17.04.2005, 14:34

I just downloaded the Moon??s Surface Map Texture named "16k moon surface dds" by Laika and I intend to use it as a alternate surface.So,I created :
Celestia/Extras/Moon clem color 16k
Celestia/Extras/Moon clem color 16k/moon clem color 16k.ssc
Celestia/Extras/Moon clem color 16k/Hires
Celestia/Extras/MOon clem color 16k/moon_clem_color_16k.dds
I wrote the Moon clem color 16k.ssc with the following code:

Code: Select all

AltSurface "Moon clem color 16k" "sol/earth/moon
{
               Texture "moon_clem_color_16k.dds"
}

But when I rightclick and choose the alternate surface,it doesn??t work (only a blank moon)
- Anybody can help me out ?
- What would methodology be using "16k VT Moon Surface" by Praesepe ?

What kind of graphics card do you have?
Older cards can't use DDS.

ATI Radeon 9200 with ATI Catalyst 5.4 for windows xp driver.
I check the gl_ext_texture_compression_s3tc in about Celestia and,yes, I get it.
Is the .ssc wrong ?
Is it anything missing ?

You'll have to tell us exactly how you installed it.
Don't leave anything out.

1. download the file" Moon_clem_color_16k.zip"(a)
2.create celestia/extras/Moon clem color 16k(1)
3.with Notepad,I wrote the code (.txt file) and saved it in folder (1).It??s name is "moon clem color 15k.txt"
4.rename .txt format to .ssc format
5.create (1)/hires(2)
6.unzip (a) in (2)
The file inside (a) is named moon_clem_color_16k.dds

Your description sounds right.
So, the problem most likely is something else.

How large is the 16K DDS texture file?
How much memory is on your video card?
Is the texture file more than half of that?

If so, you can't use that texture file: it's too big.
You'll have to use a smaller texture or a VT (Virtual Texture) or get a card with more memory.

I??ve decided to download "16k VT Moon Surface" byPraesepe.Theorically,it??s as easy as a pie : unzip it in Celestia/Extras and you??ve done.
Unfortunately,when I rightclick on the moon and chose the alternate texture, it doesn??t work.So, the problem must be the graphic card ( ATI Radeon 9200 with 128 Mb RAM).
The moon add-on takes 65 MB in my hard drive.
I get the following add-ons installed:
BlueMarble
BigHubbleCMOD
Cassiny-Huygins LandedCMOD
DeepImpact
Lera
Marsm64shaded VT
MessierGlobularClusters
Miremion
RanV2civilication
RanV2solarsystem
Real
RS Beta Hydri
RHTorvaldssun
StatgateBane
Tintin
Titan
All of them work OK
My PC is:
windows xp
ati radeon 9200 128mb ram ( ati catalyst 5.4 driver )
1024 mb ddram of memory
I??ll have to keep trying it........ Maybe some day

Just some thoughts about that i am using a Ati 8500LE 64MB Card and also that particular moon texture and i must say it works fine with me.
But i do use it as a normal texture in the highres folder, not an alternative texture.

Just a "dumb" question:
You put the texture in the hires folder, did you switch the resolution to highres too?
Another question, does it work, if you put the texture into a medres folder?

Regards,

Guckytos

Sorry for not answering Guckytos, but I resolved the problem. I made this :
1. download "16K VT Moon Surface" (a) by Praesepe.Looking through it,I noyiced that there aren??t a .ssc file so I had to create it.
2. create the following folders :
celestia/Extras/Moon 16K (1)
celestia/Extras/Moon 16K/textures (2)
celestia/Extras/Moon 16K/textures/hires (3)
3. unzip (a) in (3)
4. create Moon 16k.ssc file with the following code:

Code: Select all

 AltSurface "moon 16K" "Sol/Earth/Moon
  {
       Texture "Moon16KVT.ctx"
  }

5. save it in (1)
And, now, it works
Nevertheles,I??ll try with Laika Texture the next weekend
