Offsetting screen positioned texture background

im having trouble making a skybox similar to mario 64 where Ive thought to create a screen positioned texture that offsets with the camera perspective.

There’s probably a more efficient method to achieve what I’m looking for that I’m missing from my material any help would be appreciated.

This is the material I’ve made so far with some errors.

last but not least I’ve realized that I would want the offset limited to a certain degree of angles for the pitch but not the yaw
