Mansion wall help

[VillainousPotato]

Im making a custom story and I am using the default white mansion walls. However, when i set the walls on a corner facing out, the small lips on the top and bottom of the wall dont connect at the corner. This makes a small diamond shaped hole at the top and bottom of the wall and the player can see through it. How do i fix this?

Convex welder in static object, put that where the hole is and it should hide the hole.

Ok thank you.
