UV seams showing in normal map when rendered in UE4

[Hypnosis]

What can I do to fix this? It looks good in SP, and when I import to ue4 each uv island is receiving different lighting on the normals. The diffuse and other maps are working fine.

What program do you use? I had similar issues with modo(make sure enable exporting smoothing groups, transfer vertex map if using 801 and older), also make sure your uv texture name is not named "Texture" (default in modo). It won't remove seams at all but make them much less noticeable

can you show a pic? it could be light maps in ue4. you need two uv sets.
maybe you need to smooth edges before exporting from your modeling program.

Hi,

Can you please post a screen shot? This shouldn't be the case. A good workflow is to export the low mesh as FBX without tangent and binormals. Painter will bake using MikkT which is the same as UE4. In UE4, make sure that on import of the FBX, UE4 will compute tangents.

Cheers,
Wes

This is solved. Thank you very much. Sorry, I cannot show screenshots.
