Skyboxes

Hello,

I've been working on a 3D Chess game, So far I've added the chess board and some rotation and zooming. Now I want to add some nice background, I've tried with adding a normal mesh but it doesnt scale if I zoom out too much.

So, Is there anyway I can add a scaling skybox for when I zoom out?

What are you using for your skybox? Are you using a box or a sphere, or something else? If you use a textured sphere, you can make it as large as you want and it will look the same as long as you're inside it. If it's just a chess game, you shouldn't be zooming out too far...
If you're using lighting, don't forget that scaling an object also scales it's normals and will screw up the lighting for it.

Skyboxes arent supposed to have a distance/scale.

z-writing should be disabled when you render it, so its size is unimportant. What matters is that the camera is precisely in the middle of it.
