Worst-case scenario: the UEd Goblin wipes the map and burns down your house.
A DynamicProjector is a projector that will be detached and re-attached to level actors every time its location or rotation has changed. This is usefull if you want your projector to move, e.g. for laser crosshair or flashlights. DynamicProjectors need to have bStatic set to false and bDynamicAttach set to true.
