Hi @nosfero32 I don’t see any “distance” label in your picture so I assume you refer to the “direction” one.
Since it’s a metallic shader you’re working with I would strongly suspect it has to do with anisotropy. Basically which is the privileged directions the reflection goes (very common in brushed metals). So try linking it to the Anisotropic input of the principled shader ?
