Hard Light Walls in Portal 2.

Light Bridges are a testing element in Portal puzzles. They are a solid surface that can support the player or other objects. Despite being solid, they will travel through Grating (though not Glass). Light Bridges can be sent through portals, and can be coated in Repulsion or Propulsion Gel. Other properties include blocking turrets' line of sight to the player, and allowing portal shots to go through them.

If placed vertically, Light Bridges will effectively become walls.

Editor Adjustments

  • The position of the Light Bridge within the panel it resides on can be adjusted by dragging the white diamond shaped handle. There are eight positions for the Light Bridge.
