Box Volume

The Box shape uses an Oriented Bounding Box (OBB) — a box that supports full 3D rotation. This makes it ideal for selecting actors aligned to a specific angle (e.g., rooms on a diagonal).

tip

Use the Scale handle on the gizmo to resize the box per axis. Grid snapping from your viewport settings is respected.

Selection behavior

The box tests against each actor's bounding box:

  • In Intersect mode: selects if the actor's bounds overlap the box volume at all
  • In Contain mode: selects only if the actor's bounds are fully inside the box volume
