Static mesh "flares" up

[Fjordhoj]

Hi

I have made some static meshes in blender, and imported them to UE4
When i build the lighting, the objects emits color on one side.

It doesn’t seem that it is a specific side that lights up.
In other areas of the level it can be the facing, back, top, bottom and sideplanes that lights up.

The objects are rotated copies of each other, so i am puzzled with why some are perfect and some are not.

I have tried increasing lightmap resolution from 64 to 512, and it only does so it lights up further away.

Any ideas to what is wrong?

-how does it look like when you use dynamic lighting? -> set your lights to “moveable”
-is it still like that when you put something in front of the lit part
-which lights do you have in your scene?
-add a lightmass importance volume into your level
-make sure that there are no gaps in which the light could pass through
