Any idea why this happens?

Hahaha, I remember having these issues with Unreal Engine 1. Woooow, memories XD
Sorry mate, I never had problems with UE4 BSP so I can’t help there. But, man, this is cool.

I remember I had had the same issues in UDK.
This artefact of brush faces missing usually occurs due to one or more of the follwoing reasons:

  • Moving a vertex in geometry produced a non-coplanar brush face. Even if only temporary and the vertex is then moved to a different position, the damage ususally stays.
  • Creating a non-quad brush face (triangle prism) and subtract any other brush from it.
  • Using “Extrusion” in some cases.

How did you create/modify the brush shape?
