Celestia Forums

Hello,
I hope someone here will be able to help me...

The problem: when I try to use a dds texture as an alternative surface, the only thing I see is a blank ball! I have searched for a solution everywhere, checked out the availability of "GL_EXT_texture_compression_s3tc" feature (that is OK on my video card), but nothing helped me, I'm still not able to view dds textures in Celestia.

So, my question is: what should I do to make those dds work?

Thanks in advance!

Exactly what type of graphics hardware do you have? What manufacturer and model?
Exactly what revision of its proprietary graphics drivers are running on your computer?
Exactly what version of OpenGL does Celestia claim is available, as shown in Celestia's Help menu?

Have you tried installing any of the Addons which include DDS textures as opposed to creating your own?
Exactly what Addons have you tried? (name and download source)

Common causes of textures not being drawn are that they've been put in the wrong directory or that their names have been spelled wrong.

And don't forget that you'll need to re-install the graphics drivers provided by the manufacturer of your graphics card. Microsoft's DirectX software installs obsolete and buggy OpenGL drivers.

OK guys, still here...

First of all, sorry, I'm quite a n00b
Here some info, hope these will be useful:

- Graphics card in use: Nvidia Geforce Go 6100 with driver version 6.14.11.6003
- Running Celestia 1.5.1 on windows XP SP2 with direcx 9c.
- tried various dds textures from here, none works
- In Celestia help menu I found this: "GLSL Version: 1.20 NVIDIA via Cg compiler"

Thanks again (and sorry for annoying you)...

Get Jestr's 16K VT HERE to start with, and pay particular attention to the comments on the page.
See the read me file for installation instructions. I know that this add-on works fine on my
machine, so this might eliminate trying to guess what else is wrong.

Hope that helps, Bob

Right above GLSL is version. What does that say? Max texture size is important also. If it says 4k you should be all right to run 8k textures because Celestia will split them in half. If it says 2k then you should probably try the 4k textures. I don't know about a 16k though. I think I remember I had problems using 16k dds textures with my older card which only had a 4k buffer. A 6100 card sounds like it does have a smaller buffer, probably a 2k buffer?
