Importing/exporting from either Wings 3D or Blender to UE4

How do I import content from wings or blender to UE4?
Exporting content from UE4 as fbx to Blender works for me, but not for wings(content does not even show up)?
Wings does not have fbx format file, i think.
Importing from blender to UE4 does not work for me, it results in a crash. From UE4 to blender works with no issues that I have found so far.
What is the proper method for importing/exporting from either Wings 3D or Blender to UE4, or both?
