View Full Version : "lightning storm" module...

03 March 2008, 04:14 PM
....I wish! ;-)

been creating lighting for a lightning storm...the "flash" that illuminates the dark of the night/storm.... don't need to see the lightning itself...

the way I have been doing it is by animating/keyframing the light, from 0-100-0% intensity in short bursts or duration....about 10-12 bursts per 750 frames.

I'd like to automatically "randomize" it a bit without me having to individually re-key everything by hand and I would like to change it a bit from scene to scene without having to re-key either

any ideas? thx in advance

Try CS Tools "Flicker".

Use Xpresso, use a noise or random node through a condition node to control your lights flicker (e.g. if the noise/random output is higher than 0.8 then turn the light on, if not then off, the result will be that 20% of the time your light will be on and 80% off, change the condition value to change that percentage, change the seed in the noise/random shader to have different flickering in different scenes).
