Problem with Collision

Hey guys i have a Problem with the Collision model of my test house i made in 3ds Max.
Can i made a Collision model by myself somehow?
Because like this it’s Lookin awfull.
It’s not really enterable and some windows does not even have a collision where you can shoot through for example.

Take a look at this video: Unreal Engine 4 Tutorial: Collision (english) - YouTube :slight_smile:

Use the 1st or 3rd way → make sure to disable “use one convex hull per…” + “auto generate collision”

Big thanks for the fast answer, will try that out see if it works
