Celestia Forums

i am making another solar system to go along with my book, and i cant display my own textures. I can show other textures but not ones i made. Trying to fix the problem, I made my textures to the same parameters as the others, in this case, jupiter. I made them the same size, same filetype, but it just won't work. If there is a problem with my coding, im too much of an idiot to see it.

The code looks OK... I suspect the problem is that you're putting the textures in the wrong place. What directory are you putting the textures into? Does the celestia.cfg file point to the right Extras directory?

I think the default texture directory for Celestia (in windows) is C:/Program Files/Celestia isn't it? In there should be a folder called Textures. If you store your textures in there then they should be in the Medres folder.

However, it's generally better to store your own custom addons in the Extras directory. On line 153 of celestia.cfg (which is in the Celestia root directory, and can be edited with notepad) you should see an entry called ExtrasDirectories - that's where you define where your own textures and custom sscs and so on are.

For example, my extras directory is on my D:/ drive, in a folder called d:/celestia/extras, so in my celestia.cfg file this line says:



So you could make a folder within this called "MyAddon" and put your textures in there. I think you need any sscs and stcs in the root Extras directory, but someone else can correct me there if I'm wrong.

what i usually do is in the folder for the addon, I have another folder for textures, then one for medres textures.

Wherever your extras folder is (as advised above)....

1. create a folder called say "MyAddons"
2. create a folder called say "MySolarSystem"
3. Put the SSC in this folder.
4. Then... create subdirectories "models", "scripts", "textures", etc also in this directory.
5. Create a folder in "textures" folder called medres.
Put the textures here (and make sure they're powers of 2 in size, and check that they have the right file extension .JPG, .JPEG, .BMP, or .PNG)

The general rule is the SSC should be at the same level as the "models", "textures", etc folders.

Whenever you create a new addon, create a new folder for it in "MyAddons" and follow the same structure as above.

Also, check you haven't got any conflicts. ie. Make sure it's not created in a second SSC somewhere else which is also being loaded by Celestia. If so, disable one of them.

BMP should not be used.

My understanding is that BMP is an extremely complicated standard and Celestia's BMP interpreter implements only a very tiny fraction of it.

Also, Celestia's wildcard feature does not look for any BMP files. It only looks for CTX, PNG, JPG and DDS surface texture image files, in that order. (CTX files are proprietary to Celestia. They contain pointers to tiles for implementing Celestia's Virtual Textures.)

Sound advice. I don't mean to advocate use of BMP's. (They're too large for a start off). Just trying to give some file extensions which would at least work!

CC,

not a problem

Unfortunately, quite a few 3D modellers use BMP format for the surface textures of models intended for markets other than Celestia.

Celestia can give you some idea of what such models might have been intended to look like, but they certainly won't be shown to their best advantage.

However, surface textures should be designed using some non-lossy image format like BMP, TIFF, TGA or PNG, but only this last can be used by Celestia. The others have to be converted first (which is easy enough to do). Images stored in JPG and DDS formats have had their resolutions damaged (reduced) in order to minimize their file sizes. Those two formats should only be used for the final images. If they're used for intermediate "working" images, a lot of detail will be lost along the way.

i usually do this,



And i put all my textures in medres.
I did this exact same thing for my torzhakt system and that one works fine.

I note that your folders are capitalized...I don't know what OS you use, but this may be significant.

Thats just how I write, but the Textures folder is capitalized. I'll try changing it. Though I did the same thing on my other mod...
