| Quote (HarbingerDawn) That looks like a consequence of not specifying the parameters correctly. Are you SURE that the RAW image was 1-channel, and not 3-channel?
I tried the two values, and that's leads to the same results. I'll try IrfanView.

| Where is the surface color texture for Earth located? I've searched the texture files for Earth and the cache for likely candidates to the image, but I can't seem to find it. All I can find is the bumpmap and an odd diffmap that is transparent except for bodies of water, which it colors.

This is a color texture of Earth. It have a water mask in the alpha channel.

| If I want to add individual slices for levels 7 and beyond, what is the best way to warp a local 2D image of the area (taken from Google Earth, for example) to the same local distortion of the previous level?

| Does anyone know where Google Earth gets their elevation data or bump maps for their program? I would love to know how to obtain those to aid me in creating close-up textures!!

| Hello!
Thank you Voekoevaka for you help so far.
This is my config file:
I can see that my raw file is color when I open it in Photoshop. But when generating the tiles in CubeMap. All of then are black and white and the "base" nini sample of the raw is like a mosaic.
What could be the issue?

| Maybe try to disable normalization.
How did you create your imput file ?

| Hi,
I created the input file from a jpg image from the EarthMap.Added (05.02.2014, 04:54)
---------------------------------------------
I use Photoshop and export the 3000 x 1500 jpg picture to Raw. In the export dialog I choose Interleaved order. So the picture stays the same appearence when re-opening. When I try to reopen it I choose Channels - Count 3, Interleaved, 8 bits. Header 0. Voila'.. and the picture is colorful just like the original jpg.
But when I export using Cube... just black and white...

| There are several types of RAW. Try the others. In my case, I use IrfanView for export, and it works.

| I created a bump map for my fictional planet from Fractal Terrains (8192 x 4096) and it works perfect in-game. However when I zoom in, the planet is as flat as Kansas; even with parameters set in the .sc file. It's not flat when I remove the bump map. Is there any way to have both a custom bump map and close-up procedural landscape simultaneously?

| The bump map needs to be in cube map format to function as a height map, otherwise it will only affect lighting.
Anyway, bump maps from files aren't augmented by procedural generation, so they will always produce low-resolution landscapes compared to purely procedural planets.

| Yeah, the map's in cube map format; there isn't any issue with the planet as long as I don't land on it.
Oh well, that's too bad; I really wanted to see my purdy world up close. Are there any plans to augment bump maps from files with procedural generation in the future?

Yes, but not soon. That will take a lot of work and is pretty far down on the priority list.

| Hey !
I'm trying to create some level 7 to level 12 tiles for Earth, using celestia add-ons. But I have a bunch of problems :
♦ I was trying to blend the new tiles directly with the ones in the earth texture, but at level 6, there's styll a big distorsion between cylindrical and cubemap. So, I don't think it is possible for such a small level (maybe there's a software to do interpolation blending, starting with a bunch of points to match, but I didn't found)
♦ So I was thinking about creating a big texture with the wanted tiles inside, and use cubemap to create the maps. But there is a big problem : as I have level 12 tiles in cylindrical, it should be a very big image ! Impossible without a nasa computer...
Maybe it should be good to add in cubemap an option to process a bit of a cylindrical map as it is a very big map, and to create the corresponding tiles. Like I imput a 1024x512 image, saying it is part of a 32768x65536 map, between x=23040 and x=24064, and between y=5632 and y=3144 and I export this part in 512x512 tiles.
♦ After, it works well with grayscale and RGB images, but I never succeed to cubemapize a RGBA map : there is always an aliasing, or crashes. I use IrfanView to create these, and I think there's a problem in the way it create RGBA raw images. So it could be useful to have a png imput option in cubemap.
