Found under Actor->Triggers. When triggered, this will hide/unhide all actors with a Tag matching the ThHideTrigger's Event.

The hide/unhide depends on the ThHideTrigger's state, set in its properties under Object. Choices are:

• HideTarget - makes the target actors bHidden=true.

• ShowTarget - makes the target actors bHidden=false.

• ToggleHidden - will toggle the target actor's bHidden between true and false.

• TriggerControlHidden - trigger will hide the targets, untrigger will show them.
