When i finally made a (hi-res) moon with normal map, bump map and light map i see this in Cellestia.



I dont have this problem before and i dont now how to fix it.

Some wrong shadows in parts of moon
And this black line

I use gimp, corell 8, paint NET. to made this.
In graphic programs everything looks correct im totally confused.
I add my Tangier system to download when i finally fix this problem

Now i need some help

You don't need a normal map and a bump map, use just a normal map or a bump map.

Yes, dont need them but should use them...
Man, are you drunk?

I think you don't know what you are talking about. And I am NOT drunk!

The previous remark by CAP-Team was perfectly valid. When you specify a bump map, then Celestia converts it internally into a normalmap. It is simply incorrect to provide both a bump map AND a normalmap file name. How about explaining, what a normalmap and a bumpmap are. Then we can see whether you are informed...

AAAA...nothin to write I forget.

But i now one map show texture of surface is flat, now u make another one who show shadow and rest, and then if u want make a "light map"

I cant find where the maps are incorrect, in programs everyting looks fine.
I use 3 maps to made this object. I saw how looks like maps of water objects, mostly i saw 3 maps.

Unfortunately, English is ambiguous and is causing you both to misunderstand one another.

In common English, "normal" means "ordinary". A normal map is a image of the terrain. It might show the coloration of the ground, roadways, political boundaries, or other information about a region.
In Celestia, this is a Texture.

In 3D graphics, however, and in Celestia, it means something quite different: a "normal map" is a file which contains values of surface normal vectors.
In Celestia, this is a NormalMap.
If you use a NormalMap, you should not use a BumpMap.

A "surface normal vector" is the direction which is perpendicular to the surface of an object. As a result, a "normal map" describes the irregularities in the surface of a 3D model. It is used to help calculate shadows, making a flat surface appear to have protrusions. Normal maps are usually converted into image files for use with 3D graphics software. When viewed with an image viewer, they seem to have various shades of pink and blue, depending on the tilt of the surface at each pixel location.

In 3D graphics, a "bumpmap" contains values which are proportional to the height of a location. Celestia internally converts bump maps into normal maps. Bump maps are usually converted into image files for use with 3D graphics software. When viewed with an image viewer, bump maps seem to have various shades of grey. Their pixels are white at the highest altitude and black at the lowest.
In Celestia, this is a BumpMap.
If you use a BumpMap, you should not use a NormalMap.

Thx for explain everyting and this looooong post

Im new in making worlds for celestia but in graphic programs i sit very long time, now my dream is a buy orginal photoshop program, in Poland is very exspensive.

About this moon i made him from the beginning, long work ( i end today 1 hour ago) but when make him i finded my mystakes. Your post help me a litlle with this so very thanks for you.

This is a final version



About "drunk" i dont like when people wirte to me misunderstood post, even my eglish.

Oh yes with the likes of gimp fat chance ill be buying photoshop, there are limitations but they can be overcommed with a tad of imagination.

The best thing is having a normalmap and not a bumpmap.

That new mars is looking good.

You can upload the images now in the forum itself.

Also very important in 3d modelling, reflection maps.
(Maps that indicate how reflective a terrain is, how much per cent of the light it sends back.)

In celestia, also very noticable night maps.
When it gets dark, celestia shows those instead of the normal textures.
