Celestia Forums

I downloaded and installed 5 8K Earth textures from the Celestia Motherlode site all created by Don Edwards. The ones I downloaded are:

• Don's Realistic Earth - 8K
• Don's Earth Specular Map - 8K
• Don's Earth Cloud Map - 8k
• Don's Earth Cloud Shadow Map - 8K
• Don's Earth Night Map & Aurora - 8K

I have an ATI Radeon Xpress 1250 integrated into my motherboard and 2GB of RAM, however, Earth does not look right with these new high-res textures. Below is a sample image of what Earth now looks like. Has anyone else had this problem before and if so, how do I fix it? I am running Windows Vista Home Premium.

Edit your solarsystem.ssc and set Earth's clouds to "00" cloudspeed. You can't have 8k and them rotating at the same time. Its a limitation of Celestia.

also with this "ATI Radeon Xpress 1250 integrated into my motherboard "
with built in chipsets running all of those 8k maps at the same time assuming that the chipset can handle it will in all likely hood drop your frames/second to 10 frame pre min. (1 frame /6 sec.)
with built-in chips i would stick with 1k, 2k and 4k maps
or virtual textures
it would be interesting to see the out put of glxinfo on this machine

I find the same problem with the 4k cloud textures.

Why is it that you can't have moving clouds with any more than a 2k cloud map? I wonder if there's some way to work around it.

as to 2k and 4k clouds it depends on your graphics card, most older ones will only handle a 2k partly transparent image that is moving on the 3d object. And a built in chip set might only handle a 512 px or 1k image . The newer hi-end ( maybe?) will be able to use a 4k map
for example:
My antique nvidia Gforce2 mx 400 can have a 2k moving cloud map but a 4k non-moving map .
