Have you tried the other levels?
yes I’m trying but no way
What type of files are you importing? some formats can not be imported, or require specific settings.
I normally keep to .fbx, I import other formats in Blender and then output them as .fbx; the only problem I usually have is that Unreal will not import materials, the textures will be there so you wlll have to re-create them in Unreal - using material info from Blender (a lot of work sometimes by doable)
I think you are right
