I am attempting to get rid of this random hitbox in the corner of a building. I didn’t put it there.

You could try choosing the Union that’s causing the issue go in to properties and choosing “PreciseConvexDecomposition” in CollisionFidelity

If the above thing does not work, does the issue disappear when you sperate the union and don’t union it again?
