Hi SF,
It’s going to be a little more difficult to assist you since the material graphs are zoomed out all the way and the nodes are illegible in the screenshots provided.
I will say though, have you tried applying a vector expression node rather than a static vector. CameraVectorWS would be my first guess. (See screenshot)
Sadly that is all the advice I can offer based off the info given. Let me know if you need additional help.
