Celestia Forums

Hello everybody,

iam absolutly new in Celestia. I try to create my Earth looks like "the original" - add bumps, better textures etc, but somethin is wrong. I try to find any infromations, but iam not succesful. So, can someone help me? This is my Earth option in solar system

*START*

"Earth" "Sol"
{
Texture "earth8k.dds"
# Texture "earth8k.dds"
NightTexture "earth-night8k.dds"

SpecularTexture "earth-spec.dds"
Color [ 0.85 0.85 1.0 ]
SpecularColor [ 0.5 0.5 0.55 ]

NormalMap "earth8k.jpg"

Atmosphere {

CloudSpeed 65
CloudMap "earth-clouds.dds"
}

}

RotationPeriod 23.9344694 # 23.93419
Obliquity -23.45
RotationOffset 280.5 # offset at default epoch J2000

Albedo 0.30
}

*END*

But the image looks like this (i mean, no green, the bmp work bad, in my Celestia- i know, it is my falt, but where?):


Can someone tells me, what files (step by step) i mus use for excellent wiev? An what is best to virte in Sol/Earth config?[/img]

So,

i think, that the problem is not in the HARDWARE. I have AMD At XP 2000+, 512 MB DDR 333 RAM, + NVIDIA GeForce MX 440 (DDR 64 MB RAM).

There is log from my OpenGL from Celestia

It's *not* your fault, only a little inexperience (but that will disappear in time, i hope). I'm not the best at textures (My graphics card is far worse than yours) but I'll try to help.

Make sure the files you have referenced (earth8k.jpg, earth8k.dds, etc) are placed in one of the directories of the Textures folder (preferrably in the Hires one).
Also, as ElPelado noted, I think you must declare only NormalMap or Bumpmap, not both at the same time. Comment out with # whatever you want to disable.
I'm not sure if your "earth8k.jpg" is a NormalMap. Disable it first, and test. You can always restore it and disable the Bumpmap.

It is in the using normal map and bump map. Bug is here:


NormalMap "earth8k.jpg"
BumpMap "earthbump.jpg"
BumpHeight 4.5

but it must to be set like ths


# NormalMap "earth8k.jpg"
BumpMap "earthbump.jpg"
BumpHeight 4.5

Because is impossible to use both ) Iam stupid )

By the way, you were using your earth texture(earth8k.dds) as a normal map. you werent using a normalmap.
try to find another normalmap in the internet and you will see how they look like.

Can U give me the best URL for best wiev? Thanx...

sorry, but i dnot know. my video card is not the best, and i dont have the best textures for earth. and i dont even know where to find them. try searchinf in the "textures forum".

here you have a normalmap of the moon, to see how it looks like:

Hi kary,

First a question: Can your GF 4 MX show effects like bumpmapping and specular reflections (has this card pixel shadder and vertex shadder) ? I'm not sure.

If that's so than I recommend to use a 4K bump map ( JPG or PNG format ). A 8k map needs 170mb (grafic-)ram and that's to much for the most sytems.

The possibility to use normal maps instead of bump maps is relativ new to Celestia and only the latest version ( 1.3.1pre3 ) works correct with these. Therefore you will probably not find a (correct) normal map for earth at the moment.
Keep your eyes open until Fridger update his texturefoundery and I think there will be nice nomal maps.

Bye Jens

The Geforce 2 MX does specular and bump mapping (hardware pixel shader, software vertex shader) so presumably the Geforce 4 MX can too.
