I downloaded the textures,but they didn??t work in Celestia 1.5.0 pre.
I think Celestia has a problem with VT textures in .png format...

hear are the links

http://www.filefactory.com/file/398709/the bumpmap is a 16 bit unsinged .gray image
I work with unsinged and not singed images
here is a hack for using unsinged images in nms
Code: Select all
short readS16(FILE *in)
{
short b2;
fread(&b2, 2, 1, in);
if (byteSwap == 1)
b2 = (((b2 & 0xff00)) >> 8) | (((b2 & 0x00ff)) << 8);
return (short) (b2 +32767);
}

The textures work just fine for me in 1.5.0 pre2. I used the base map and the normal map. Some work was needed to put the textures in their proper folders, create the .ctx for the normal map and the .ssc for the alt texture. It looks properly aligned to me, and looks quite detailed, although it's fairly obvious where the edge of the "limit of knowledge" is. Probably not easy to do anything about that though. Thanks for your work John.

John,
While .ctx files are easy for you and me, Celestia novices have not the slightest idea what to do with VT files. They see that they're supposed to make planets look better, so they download hundreds of megabytes of stuff, and then can't find any way to get them to do anything at all. So far as they're concerned, you've made them waste time and bandwidth for no purpose whatsoever. It's extremely frustrating for them.

Could be hardware compatibility.You have a MONSTER COMPUTER,with dual core,lots of RAM and even 512 MB of video.Maybe this helps or maybe you only get it by chance...
Anyway,I put the VT straight in the solarsys.ssc and didn??t create any ssc.But the problem is even for non begginers,it??not that easy to create VT textures,because your VT texture should be adjusted to the specific normal texture and not for a generic normal texture...
