Looking to emulate lightning strike

[proudmer22]

Hello!
I want to emulate a lightning strike for player(Scene happens in the middle of the storm).
It's not nececcary to spawn the lightning itself - I just want to brighten up a screen a little(a flash).
I don't know where to look for this.Any tips?

You mean like in the fourth mission of the Sentinel campaign ? Those flash lightnings that occur from time to time ?

Exactly! Thanks.

Blizzard used the "Cinematic - Fade Filter" plus "Play - Sound" actions to do it. Here's how they did the "Occasional Lightning" from map NightElfX04:

• Occasional Lightning
  • Events
    • Time - LightningTimer expires
  • Conditions
  • Actions
    • Wait until (InCinematic Equal to False), checking every 1.00 seconds
    • Countdown Timer - Start LightningTimer as a One-shot timer that will expire in (Random real number between 25.00 and 60.00) seconds
    • Cinematic - Fade out and back in over 0.12 seconds using texture White Mask and color (100.00%, 100.00%, 100.00%) with 5.00% transparency
    • Wait 0.03 seconds
    • Cinematic - Fade out and back in over 0.12 seconds using texture White Mask and color (100.00%, 100.00%, 100.00%) with 5.00% transparency
    • Wait 0.20 seconds
    • Set RandomSound = (Random integer number between 1 and 2)
    • If (RandomSound Equal to 1) then do (Sound - Play LightningBolt1 <gen>) else do (Do nothing)
    • If (RandomSound Equal to 2) then do (Sound - Play RollingThunder1 <gen>) else do (Do nothing)

Do note that the timer from the event above is started in another trigger once the very first cinematic ends.

• Countdown Timer - Start LightningTimer as a One-shot timer that will expire in 30.00 seconds

Here is a good tutorial with some nice ideas. I kind of combined them for my maps.

Lightning Flashes - Environmental Effect

Sorry I was not clear - I already copied the trigger from NightElvesTFT04.
On my map the effect seemed to be a little epileptic-non-friendly so I increased transparency to 80%.
Thanks everyone!
