never mind, i just found it

I've uploaded scaled down versions of the Mars v3 shaded map, you can grab them here:

Okay people, after a while (my new job as a computer technician does not give the time i'd like to have for Celestia ) here it is in what I'm into now(finally).. a 16k normal map(virtual texture, dxt format) for Mars. Here are some screenshots :

praesepe,
Is it just me or is your NormalMap invrted. Maybe you loaded the wrong one for the pictures? In most of them features that should be dugg into the surface looks like uplifts and Olympus Mons looks like a crater. Just thought you might like to know about this. I am sure I will not be the only one pointing this out.

this is the alternative texture 6meg layers 0-4 only - still blows the doors off 8k normal, and probably rivals 16k.


This is a fast link.

Praesepe, I agree with Don. The lighting gradient of the overal planetary surface seems to disagree with the lighting on the features.

Also, is the graininess a property of the texture, or of the screenshot images?

Cheers,
Paul

The graininess that looks like worms on the surface are an artefact when using certain dxt formats for normal maps. This has been discussed elsewhere.

Both of you, Don and Paul, are right. I've accidentally did an inversion of the red channel in some point of the process (this is what happens when you try to do things in a very short time.. ) but this fill be easy to fix, I'm doing it right now

Yup, this is due to the dxt compression.. I've tried with dxt1c and dxt3 (with a little of improvement in the last one) but is hard to fight with this noisy grainness Although the graniness, the last levels have a good detail level, specially when using dxt3 compression.
