# Light Effects

Tarquin: page duplication with Actor (UT)/Lighting – sort of. How much has changed form UT to UT2003?

Foxpaw: Most, but not all, of these still work for dynamic lights. Static lights - basically none of them work right anymore, due to the fact that lightmaps are pregenerated and can't be animated through the use of lighteffects anymore.

Tarquin: Ok. So do we need one page for UT, one for Ut2003, or will one page do for both? How about I move the list & images from Actor (UT)/Lighting to here?

Foxpaw: I think that's a good idea. One could also add the lighteffect "QuadraticNonIncidence." I'm not sure what it does but it seems similar to NonIncidence.

## LightType Properties

LT_None
  No lighting. Why you should use this for lights is beyond me!
LT_Steady
  Normal light. Probably the one you'll use most often.
LT_Pulse
  Pulses the light on and off. Imagine playing with the light dimmer switch.
LT_Blink
  No effect observed as of yet.
LT_Flicker
  Good for broken down factory-type areas. Flickers on/off, as if the light ws broken. I don't know if it works with Coronas.
LT_Strobe
  Flashes light on... off... on... off... Whee! Headaches! Not really suitable for gameplay...
LT_BackdropLight
  Possibly used in SkyBoxes, but I dunno. No effects observed.
LT_SubtlePulse
  I find this to be good with Green Lighting against Slime pits. Just barely noticeable, but it's there. Pickups are lit in this way.

## LightEffect Properties

LE_None
  Standard light.
LE_TorchWaver
  Subtle fire effect, as though it was a torch.
LE_Fire
  Normal fire effect, as though it was an actual fire.
LE_WaterShimmer
  Set lighting to this underwater for interesting results.
LE_SearchLight
  A rotating light. Not much to this.
LE_SlowWave
  This'ld be good for a light just above water, methinks. Sends out slow waves of light.
LE_FastWave
  Sends out fast waves of light.
LE_CloudCast
  ??? No apparent effects.
LE_StaticSpot
  Ditto.
LE_Shock
  Like LT_Strobe, only faster.
LE_Disco
  Random "disco" lights, the type of lighting you see in n00b maps.
LE_Warp
  ??? No apparent effects.
LE_Spotlight
  One spot of light. Remember to rotate the light actor to get this where you want it.
LE_NonIncidence
  As if all solid surfaces were made out of jelly, or invisible, light passes straight through them.
LE_Shell
  Gives a "The Ring" effect, only lights up the edge of the radius.
LE_OmnibumpMap
  Yikes. No apparent effects.
LE_Interference
  Like SlowWave/FastWave mixed together, except differs according to the textures.
LE_Cylinder
  It's a cylinder of light instead of a sphere.
LE_Rotor
  As if a fan was in the way between the light and the surface.

## Changing The Effect

LightPeriod = changes the speed of the light.

LightPhase = Which frame of animation the light's on.

NOTE : Remember all light effects will significantly decrease performance on your map! Use sparingly!
