I don't have the problem, but some people reported me the issue. I think its an issue with the NM layers how can i fix it? Thank you
Then maybe do this first, with low merge distance like 0.0001 or smth., then try that normals stuff again if still not, then maybe the normal-map is bad, try ksPerPixel shader without one hint: assettocorsa\sdk\dev\car_pipeline_2.0rev\Photoshop Action\Normal_MAP_Rotation.atn
