1) Choose the color of the ambient.

In my campaign, i chose VX Stormybrood. This is the lighting set that appear in the ambient... I think you understood. Nothing special here. you can change, if you want. (this lighting set can be found in the download section.)

2) Creating the first triggers.

Create a trigger, called STORM BEGIN:

Active, High priority.
Effect: Sound filename "cinematics\35_in\thunderstorm.mp3", fire event "LIGHTNING1"
-----------------------------------------------------------
Create a trigger, called THUNDER:

Active, Loop, High priority.
Condition: timer 80 secs (don't change this!)
Effect: Sound filename "cinematics\35_in\thunderstorm.mp3
-----------------------------------------------------------
Create a trigger, called LIGHTNING1:

Loop, High priority.
Condition: timer 18 secs. (this is the frequency you want the lightning.)
Effect: Set lighting VX Twilight (or Eclipse)
Fire event: LIGHTING1 END

3) Making it works.

Create a trigger, called LIGHTNING1 END:

High priority.
Condition: timer milisseconds 200 (really fast)
Effect: Set lighting VX Stormybrood (the original one!)

3) Improving your Storm.

Create these triggers, creating 4X of them (example), and use them with different timers (try making numbers that wont match so easy, like 18, 27, 12...)
---> Use some rain, if you want.
---> The sound and the light wont come together, like in nature.
---> If you prefer, REALLY PREFER, you can use Sound filename (thunder sound) after each lightning. So, it's easy and it wont hurt.

IF YOU WANT THE BOLTS, SET GAIA TO INVOKE SPC LIGHTNING STORM.
