Portal Gun - Aperture Science Handheld Portal Device

I'm no longer offering support for this addon. Sorry, everyone! Use at your own risk.

A fully functional Portal Gun. This is by far the most eloquent and bug- free portal gun available within Garry's Mod.
Left click to shoot a blue portal. Right click to shoot an orange portal. Reload to remove all portals. Press E to pick up an item.

TO MAKE THE PORTALS LOOK AS THEY SHOULD, RUN "r_novis 1" IN CONSOLE.

IF YOUR PORTALS ARE WHITE OR BLACK, YOU MUST START THE PROGRAM WITH -dxlevel 90.

Windows is currently the only supported operating system.

Please refer to the second video above for instructions if you are having trouble.

• Portals which look exactly like the portals in Portal 1
  
• Walk through portals just like the game. No more poofing!
  
• Standalone, does not require Portal or Portal 2 to work correctly.
  
• Velocity is (almost) entirely preserved as you enter the portal.
  
• Optional dynamic lights
  
• Several convars to adjust the portal gun to your liking (listed below).

• portal_arm <0|1> Whether to render the arm of the portal gun's viewmodel. (Default 0; requires portal 2).
  
• portal_beta_borders <0|1> Whether to use different textures for the portals. (default 0)
  
• portal_borders <0|1> Whether to render portal borders at all (default 1; 0 somewhat improves performance)
  
• portal_crosshair <0|1> Whether to use the portal crosshair (default 1)
  
• portal_dynamic_light <0|1> Whether to use dynamic lights with the portals (default 0; 0 drastically improves performance)
  
• portal_limitcarry <0|1> Whether to limit the portalgun to pick up portal props only (default 1)
  
• portal_projectile_speed <number> The speed of the projectile shot by the portal gun (default 3500)
  
• portal_render <0|1> whether to render the other side of the portal (default 1; 0 drastically improves performance)
  
• portal_vm <1-5> Changes your viewmodel to one of several options. (default 1)

• Portal projectiles don't exist in multiplayer
  
• Multiplayer in general is very unreliable
  
• Props sometimes fall through the floor when they move through the portal
  
• Roof portals don't preserve velocity for players.
  
• Skybox sometimes doesn't draw within the portal.
