You make them with a 3D modeller, such as Milkshape. It simply a box, with the texture on the inside. If you need more help at this stage, you need to look into the modeller you are using, not DB.

You don't "lock" them into position. Put it in your scene, resize it to something suitable, then keep it centred at the camera position. This way, you never reach the each and see crappy, jagged graphics, it's always in the distance.

Hope this helps get you started.

The Most Simple Way To Make A Skysphere Is To...

Make Object Sphere [size](Make The Size A Negative Number),[Object Number]
Texture Object [Object Number],[Texture Number](Because The Sphere Has A Negative Size, It Textures The Inside)

Then, Near The End of the Main Loop, Type...
Position Object [Object Number],Camera Position X(),Camera Position Y(),Camera Position Z()

Make Sure The Size Of The Sphere Is A Negative Number, And Large Enough That You Can Still See The Distance You Want. You May Also Want To Add Fog, And Set The Skysphere So It Is Not Light or Fog Sensative.
Well... I Hope That Helps.

What does that do, I'm intrigued.

Another technique I've seen is to set culling off, so the Skybox can be smaller than your camera limit, but the scenery shows through it.

Hmmm... Setting Culling Off My be a good idea also...

If you set the skysphere's size to a little less than the camera limit and add fog it will make objects far off gradually appear instead of just appearing due to them being outside the skysphere and/or camera limit. You have to set the skysphere fog and light sensativity off so you can still see the texture through the fog, and so the sky doesn't get darker or lighter because of lights in the scene.
