Collision for House?

i have imported a house which i want to use in my project,but i am having issues regarding collision,
i have tried every collisions from simple box to convex but none fits (Because i cannot enter the house from door),the collision blocks the door side,is there any way to use whole mesh as collider??
Like unity or back in UE3??

You can use Complex as Simple collision by opening the Static Mesh editor > settings panel > drop down box for collision > set as Complex as Simple.

This will use per poly collision. It’s still more efficient and overall better to use custom collision or simple box geometry made up of many simple collision boxes though.
