DUMMY
From TRLE Wiki
A DUMMY trigger is a trigger that does not activate anything. It is used in combination with some objects where Lara can stand on. Those objects require a trigger below it to avoid Lara falling through. If no real trigger for the object is needed below it, a DUMMY trigger can be used so the object won't be triggered when you walk over it, but Lara can walk over it.
Some objects where a DUMMY trigger can be used are:
As with any trigger, the DUMMY trigger has to be placed on the floor below the object. If there is a door below the object, the trigger has to be placed in a lower room, directly under the object.
