[Godot 4.0] Shader only works if the mesh is pointing towards Z+

Mesh pointing towards positive Z:

Mesh pointing towards negative Z:

Changing
vec3 I = normalize(vertexW - CameraPosition);
to
vec3 I = -normalize(vertexW - CameraPosition);
Makes it work pointing towards -Z.

Pointing it towards X- or X+ also makes it not work.

Hello @kimamb ,

I am aware of the issue, and already working on the fix, I am trying to simplify the new implementation so it can perform well in large scenes.

Thank you very much.

I am looking forward for the update!
