Object looks strange after light build
I have a strange issue, I built a couch in Blender and textured it with substance painter. In Blender and Substance Painter, everything looks fine. It also looks fine after importing it to UE4 and setting up the materials, but after building the light, it looks totally strange, see .
It looks like an issue with the UVs, but UE4 does not complain about them while importing. I am using Blender's Smart UV Projecting with the default settings. I joined all objects together before unwapping.
I only have this problem with this model. Any ideas?
Thanks for your help!

I guess when "you" lay down your uv islands you use an automatic flatten map... well those cuts you see are the same as on your (lightmap) uv islands! Yeah you can raise your lightmap resolution and those will disappear by time... BUT a better solution is to have a proper lightmap with a proper resolution! ;) Keep rounded surfaces together and have those cuts where it's a hard edge or where it's not visible!

Stich your UVs to avoid this issue.
