Celestia Forums

Hi,

I have two problems with Celestia 1.3.0pre3

1) Athlon 1800+, WinXP, 256Mo, NVidia GeForce2 MX 400 64mo
I just can see IO texture but no others (grey jupiter, blue saturn, black earth ...)

2) Toshiba Tecra 8100 PIII 800, NT4, 256Mo, Video S3 8mo
With the same program, textures are OK
But Celestia crash when I try to see planet with rings (saturn, uranus)
with the error : the instruction at 0x00000000 referenced memory at 0x00000000. The memory could not be read.

Apart from this, on Athlon I use Celestia 1.2.5 with high res
Texture "NewEarth4k.dds"
NightTexture "earthnight4k.dds"
BumpMap "Earth2KBump.jpg"
CloudMap "earth-clouds2k.dds"
and extended stars DB "starsdb2_0A.zip"
Really nice

Celestia 1.2.3 low res runs well on Toshiba PIII
with extended galaxy_and_clusters.dat.

Wonderfull work !!

The first thing you should do is upgrade the Nvidia drivers to the most recent release. v41.09 provides OpenGL V1.4 and is freely downloadable from http://www.nvidia.com/content/drivers/drivers.asp Unfortunately, it's a 13.5MB download. Older versions of the drivers don't work very well with Celestia. (download new drivers, set a "recovery" point, use "add/remove programs" to delete the old ones, reboot, install new drivers, reboot, configure screen)

If you haven't already done so, you should upgrade the S3 drivers, too. http://www.s3graphics.com/DRVVIEW.HTM

By default Celestia tries to use all of the features that the drivers claim to support. Too often there are bugs in the more sophisticated routines. It will select a different "rendering path" each time you type a "Ctrl-V" The "Basic" rendering path should work for all cards. Does Basic have the problems you report?
