Making vray lights randomly adjust their multiplier

[stelees]

Hi everyone,
I know the answer to this is wiring the parameters but I just can't make it work.
For my daughters major works presentation, she wants me to do a looping animation for the various headings of her talk. In a nutshell there is a plane, the text of the section extruded sitting just above the plane and behind it there is a wall of vray disc lights. The bloom is turned on and the multiplier is up around 100 for them, so it's like that over the top night club wall of lights in your face effect. What she wants me to do is one of two things.

break up the lights into 4 groups, so maybe 5 across and 8 down and adjust, pulsate the lights so the groups are strobbing OR
randoming adjust the brightness of all of the lights so they are just flashing the whole loop.

I just need some help understanding how to make either of these happen over about 50 frames or so.

Many thanks from the dad of a very stressed daughter

You can add a noise controller to the lights' multiplier.
Alternatively, would you want a more controlled pattern, you could manually keyframe one intensity, and copy/instance the animation controller over (perhaps shifting it forward and backwards.).

If it is just a black background and you don't have to see the actual lights so to speak and just need a bunch of random blooms, it may be easier and faster to build it in something like after effects using lens flares and a wiggle expression in the intensity.

Other than that, what Lele said with setting a few manual key frames, copy/paste them along the timeline so you can have a clean loop with the start/end having the same intensity, then copy/paste the keys to the other lights.

In the past if I needed something easy, quick n dirty I've used the reaction manager to link a slider to lights like that, esp if there are several groups. Then its easy to animate the intensity just using the sliders.
