[li]Brightness (renderamt)[/li]
[li]Beam Color (rendercolor)[/li]
[li]Radius (Radius) - Noise radius.[/li]
[li]Life (life) - Time for beam to stay on, in seconds. 0 is infinite.[/li]
[li]Width of beam (BoltWidth) - Width of beam in (pixels*0.1). Range: 0-255.[/li]
[li]Amount of noise (NoiseAmplitude) - Range: 0-255.[/li]

[/list]

Flags

• Start On (1)
• Toggle (2)
• Random Strike (4)
• Ring (8) - Forms a ring between the two targets.
• StartSparks (16)
• EndSparks (32)
• Decal End (64) - Decals (bullet holes) appear where the beam hits objects.
• Shade Start (128) - Start of beam fades away
• Shade End (256) - End of beam fades away.

Notes

• Info_target entities can be used as the beam start and end points when the Ring flag is off.
• Only some point entities works as end and start points for beams with the Ring flag on.

For example, monster_barney and weapon_rpg entities works, while light, info_target and path_corner entites does not.
All brush entities with an origin brush works, though.

• You can create moving beams by using func_trains as the targets, but they need an origin brush for the beam to aim at.
