Normal Map showing seam around uv borders

[amar253sharma]

Hello , 

I prepared a Model In zbrush and bake out normal map from there .......But when i bring the model into Maya and plug normal map in it ....then a very bad  normal map seam appears on my model  around the uv borders .....I am using Maya 2020

I set my normal map  color space to raw and I used bump node as a Tangent Space normal but there is still bad seam ......I think my uvs are fine and i plug maps in correct way and My model Topology is Also fine .But there is seam appears ......I am attaching my project file ...Please help seamseamMy uvsbaking setting

If you have a seam in the uvs you need there a hard edge in the lowpoly most of the time.

You need the tangent space synced. That means if you need the map in maya bake in maya.
If you need the normalmap in ureal you need to bake a mikkt normalmap. There are many different kinds of normalmaps.

If the tangentspace isnt synced you get seams.
