Portal 1 Styled Portalgun Glow Addon

This is my attempt to recreate portalgun particles from Portal 1. Archive contain 2 versions of this addon: Dark - Slightly more saturated version. Emit no light while portals are not in use. Bright - Slightly more bright version. Emit faint gray light while portals are not in use. WARNING: If the game speed is slowed down enough or your framerate become higher than 600 fps, the particles may start to flicker.
