i've done the google thing and haven't found too many.. basically only one from the hazy mind website. does anyone have any other tutorials or could you point me in any other direction for help on this subject? i've created a face object .. which i then create an array of in my skybox class.. each face object contains 4 PositionTextured vertexes etc to make up the wall with the right texture/image. my real problem is rotating the walls into …

Dont let skybox's confused you. They are nothing more that 6 large-textured quads.

I will include my code for my skybox. You can draw a skybox with much left code than how i did it.
