Unwanted holes in imported FBX mesh
Hello! So I've been working on a school project - trying to combine point clouds renders of a house, surrounded by mesh walls (with auto-collision) to create a game environment. So far I've had success with importing the point clouds using a UE4 plugin, but importing the meshes I made in Autodesk Maya has been a bit of an ordeal.
Here's what the model looks like in Maya:
Solid, with no holes other than the intended stairway ports. However, when I export the model as an FBX and try importing into UE4, this is the result:
For some reason the imported mesh now contains holes that start from the intended openings and stretch towards the outer walls. I've placed a player in the scene and walked over these holes - though they it seems like you'd fall through, the mesh is solid and still contains collision. If the mesh was was going to be invisible this wouldn't pose much of a problem, but I need the mesh to show in order to separate the various rooms of the point cloud.
I've tried various import settings (uncombined mesh / no auto-collision / etc.) but nothing gets rid of these holes. I'm new to UE4 so I'm sure I could be missing something simple, but I'm at my wits end trying to deduce what that might be. Any tips or suggestions on how to correct this import issue??
I appreciate any and all help, thank you!

Triangulating those objects in Maya then re-importing into Unreal fixed the issue!! I think there was an problem with smoothing groups, but I'm not exactly sure... Either way- it's fixed! Thank you guys for the help!

As far as I get this it maybe worth trying importing the mesh directly to the engine, without the plugin, and in the import settings uncheck 'Remove degenerates'. This feature removes ngons out of your mesh. Probably, that's the reason.
