I'm a freelance game designer, and I can't afford to hire someone to do skyboxes for me.

However, I am unable to do them my self.

Let's say I have a texture that can be tiled on four sides...

If I put that very texture on each side of the skybox.. It just comes out looking like a cube.

I'd like to know how exactly I need to "warp" a texture, so that when applied to a cube on all four sides, it looks spherical.

Thanks! -- G


You might want to take a look at Sky Domes. Due to their shape it's a lot easier to get a decent result.

Here you can find a tutorial on how to implement it:


And here's a very nice example of how it can look like if you put some work into it:


  • \$\begingroup\$ I'll take a look! The only problem is that the engine I have does not have skydome support built into it's rendering engine -- I'd have to do something like place a large dome over the entire world. Also, I need it to be fully immersive -- The bottom is actually just as important as the top of whatever background method I use. \$\endgroup\$ – Georges Oates Larsen Oct 28 '10 at 17:48

Why don't you try Terragen? It's a terrain generator that allows you to render to the six faces of a cube and save the images to use them as a skybox.



If you are a programmer talking about skyboxes, I assume you have some knowledge of the 3D engine / librairy / tool you are using. If not, you should ask questions about this engine / librairy / tool to get help on how to create such a skybox (I mean, the programmer job of creating the entity correctly).

Otherwise, all you need is a nice texture to apply to your skybox and there is plenty of websites that will offer you free textures for you to use in your project.

Here are some that I've found :



Here is a tread on BlenderArtist and another from GameDev about it :



  • \$\begingroup\$ Those are some REALLY cool links! But unfortunately, for this particular project, none of them will do. I specifically need to be able to warp a texture so that it fits onto a skybox, and looks spherical. I have taken a look a the program's built in skybox generation tools, but they always come out with some form of defect (Huge horizontal stretching, or tight pinches). \$\endgroup\$ – Georges Oates Larsen Oct 28 '10 at 17:53
  • \$\begingroup\$ Would you be searching for skydome textures perhaps ? \$\endgroup\$ – Frédérick Imbeault Oct 30 '10 at 16:34
  • \$\begingroup\$ Nope, certainly not. Unity3D has the ability to warp textures into skybox applicable textures, but they do not come out well at all. \$\endgroup\$ – Georges Oates Larsen Mar 1 '11 at 4:56
