Ok, also I have create a sky box like the sky box in the vertexprogramm example of osg. But in my scene the up vector is in the z direction and not in the y direction. Now I have rotate my sky box 90 degrees around the x axis.
Is it understandable? But now, the images on the sky box are in the wrong orientation. For example the image in the positiv x direction is 90 degrees rotated. And I want to correct this rotation. Is it understandable? I am not sure.
