An env_portal_path_track beam (top) versus the final effects (bottom)

env_portal_path_track is a point entity available in Portal (series) Portal (series). It is an unfinished variant of path_track which produces a visible light rail along the path. It was presumably meant for the Unstationary Scaffold, but the final game uses regular path_tracks and env_beams for this.

Icon-Bug.pngBug:A func_tracktrain cannot start at an env_portal_path_track. It can still follow them as long as the starting node is a regular path_track.  [todo tested in?]
Icon-Bug.pngBug:Copying an env_portal_path_track in Hammer will not automatically rename it or link the previous node.  [todo tested in?]
