DDS Files & 3D Models

[cacjardy]

Hi,

I havn't been able to get 3D planet models working with DDS textures.

With Mars_1x, my 8k Mars DDS map is white all over.

Is there some kind of fix?

That means that Celestia cannot find the surface texture images. Textures specified within model files must be in the medres folder. Some other possible issues are described at http://www.lepp.cornell.edu/~seb/celest ... tro.html#6

I have found that the texture works with a single .png file, but not with a DDS or VT.

I have tried numerous ways of getting this to work, but all have failed.

I have a 3d model of Mars at the Celestia Motherlode called "3D Mars". Is this the model you are using? A dds texture should work on that model but you have to rename it and it must not be a VT. The model looks for a texture called mars.* where star could be dds. So you would have to rename the full dds texture of mars to mars.dds. Also A VT texture does not work on models.
You also must use a texture that will fit into the buffer of your video card or Celestia will make a VT out of it and it still won't work. Check the "Help" tab from the toolbar and click on Open GL Info. This will have a field called "texture size" and you'll have to use a texture equal to that size or smaller.

I didn't supply a texture with that model. One way to use:
Download one of the mars dds textures from the Celestia Motherlode. Download one that is 8k, 4k or 2k depending on the maximum texture size supported by your video card. Create a new folder in the 3dMars folder called "textures". Then open the textures folder and create another folder called "medres". Then put the dds texture of mars there and rename it to mars.dds.

Another way is to edit the ssc file. Replace the line Texture "mars.* with Texture "name of the file you are using".

Thanks for the help. I found out the DDS file I was using was corrupt, so DDS files do work.

That's sad about VTs not working on 3D models. That may be a thing to fix in Celestia 1.6.1.

Probably not 1.6.1. Maybe for 1.7 though?
