Baking normal in substance create artifact

[Kenny323085767u4t]

Like the title said, baking in substance crate weird artifact 

|
From Blender, I have tried reseting normal, resize the baked UV size (in SB), soften the edge where this problem occur. But the problem still presist/ 
The UV and model.

I have try to solve this bymanually remove this artifact through painting the normal in SB, But this is really time consuming.

Hi Kenny,

Thanks for the detailed message.

I advise you to add a UV seam at the edgeloop where the issue occurs.

Let me know if it helps.
