Ok then, Is It possible to make a texture for a galaxy in GIMP though? I do not have the money for photoshop.

Ok so can i use other than photoshop for my custom textures?

I think GIMP is a program more than adequate for the task, plus it's free and open source.
Another free, simpler, but equally useful program could be Paint.NET.

Ok thanks i do have paint.net, But how do i remove the background stars on paint.net?

By deleting them? I guess you need to know how to select with lasso tools and similars, but this quick mask trick could be useful:

I am having trouble with the sys image and the dust image for the galaxy. How do I make the dust and the "subsystem" image?

Where do i put the custom textures?

Are there any forbidden characters in planet or star names?

How do you make a galaxy model? The Manual doesn't explain it well.
My model just comes up as an egg shaped object.

I made the nebula model and textures but it didn't work.
Did i do something wrong?

Oh wait i figured it out
Thanks anyway

Nevermind, my galaxy comes out as a cube of dust though. I might show a snapshot so anyone can see how it is right now, how do you fix this?

Arturo100, if your galaxy is a square of dust that means something is wrong with the alpha channel on your texture. The instruction says how to make it.

Never mind again, still though why does the “CubeMap” method make a dust cube for me?

Also is it possible to make the interstellar dust pattern in GIMP? I don’t know how to do it.

Arturo100,I dont know about gimp. You can check, if it can save images in TGA with alpha mask than it will work.

Ok, what do I name the file though? Like the end, an example Galaxy_sys.
Oh about the dust cube, I did not realize the backround which made the galaxy a dust square, I might stop commenting for now.
