Bevel mimic by material

I need your help with normal vector operations.
I am struggling with the Bevel-Mimic-by-Material and have lack of the basic knowledge about normal vector transformations.
This is my current formula and one side of the mesh has very nice bevel results. But the other side is a mess.
How to change that formula to propagate the bevel to the other side of the mesh?
(that what is black is ofc wrong - I have attached Normals to the Color channel to visualize the bevel creation )

Hello, did you find a solution? I’m currently trying to mimic a bevel in the material, with no success as of now
