I want to move nyc 2259 level to my new unreal c++ project

[Kong]

I tried many ways. 

First, I moved all files and folders in Content folder. But when I open the project all building's light was gone.

And for second I tried using migrate, but the result was same. 

And there are some warnings, but I wouldn't solve this problem alone..

Anyone knows about this??

I solved this! I was migrate only level, but there was a warning message that can't recognize wall material so I migrate this material too. NOT export!
