Getting strange artefact when baking low poly normals in Substance painter.

Sayooj_js

I clearly haven't any clue why this is happening inside substance painter when baking low poly normals. When I am trying to Unify the normals from 3Dsmax changing the smoothing group's values.

I think those artefacts might appear because of your topology, based on the images you provided.
Try adding some support loops. Are u using a highpoly model to bake from or nah?
If not maybe you could provide us with your mesh so we can take a closer look.
