@presto423 thanks again for the heads up
Because of your post, I did a test export.
The Blender>Unreal pipeline seems to be working cleanly on my end (I think).
I just tested my newest Blender 2.8.(3?) FBX export, and it seems to import well.
For reference I’ve attached a few images for others who stumble on the thread.
UE4 generated nice light-maps for me – It makes decent space of the original UV (with some padding).
I guess I’m splitting up every poly in column model. I’m a n00b. (UV 00 and 01)
The Blender auto UV is still pretty nice though for quick objects and rookies like me.
Back to the homework 
p.s. not sure about the smoothing group warning. That’s a 3DS MAX terminology isin’t it? Maybe that’s crease line in Blender?
