i just started to port over my UDK Stuff to UE 4. So i exported all meshes as .fbx and exported the Textures as .tga. After i imported them and reassigned the Materials i always get an arror when building my lightning.
Strange thing is i never had any UV Problems with that content in the UDK. After building the lightning the shadows looks weired then of course.
Any help is appreciated
