Description:In Unreal Engine 5.8, the box (marquee) selection subtract functionality in the Level Editor has changed and is no longer working as expected.Previous behavior (UE 5.7 and earlier):
Holding Ctrl + Alt + Left Mouse Drag would perform subtract selection (remove from current selection). This was a standard and efficient workflow.Current behavior in UE 5.8:
- Holding Ctrl before starting the drag now triggers object movement / duplication instead of selection.
- The only way to subtract with box selection is to first start dragging with LMB, then press and hold Ctrl while dragging, and finally release the mouse button. This is very cumbersome and breaks muscle memory.
