Entities: collidable_geometry

This entity is a brush entity. This means that its size and shape are defined by the solid(s) that constitute it in Hammer.

This entity is used to construct level geometry. The game uses its faces to perform collision detection. If this entity is made dirt, portals can be placed on it (provided it has sufficient size). Any faces painted with the texture 'aaatrigger' will not be rendered or collided in game.

This entity is more flexible than a func_wall in that faces of any orientation can be used as geometry, rather than just faces along one axis.
Properties:

• SFX Type (sfx_type) - Defines the type of sound to play for collision and footstep events. If set to 'Dirt', allows placement of portals on its faces.
