Just a bit of Help really, I’m a total newbie when it comes to Game Design engines etc etc and am learning via YouTube and other videos 
Could some tell me why UE4 does this weird culling thing when placing BSP’s inside others when blocking out a map for example?
This only seems to happen with “solid” BPS’s when I changhe to “Semi-solid” the issue seems to go away.
Any help / info greatly appreciated
