artifact on the normal map imported into Unity

Unity Engine
1

Hi guys,

I have a problem with the normal map imported on unity.

On substance painter, the normal map is acceptable.
On units the normal map is horrendous.

Why is this happening?

I did some tests, with different configuration of export from substance painter and import on unity. the artifact is displayed when I insert an HDR. I don’t see the error with the default unity sky.

if the object on unity is configured as static with an hdr, the artifact seems to improve, but to a certain extent, it always remains there.

IS IT A PROBLEM OF NON-SYNCHRONIZATION BETWEEN SUBSTANCE AND UNITY?
IS A PROBLEM OF SETTINGS TO SET ON UNITY?

Seems like red or green channel of normalmap inverted. Invert it in 2d application manually or change export normalmap settings.
