Animating light coming on blinking...

[Terri Brown]

Hi guys,

 

So I'm on my first big animation project. A bit daunting as I've always focused on stills...plus it's just me, so I'm in need of picking your brains. I have a 4 second shot of a gym area. I want to intro it dark, and then animate two separate tracks of spotlights to come on and light up the scene. Here's a test still, with the separate tracks shown (A & B...and possibly C afterwards). I've managed to switch the lights on (basic) (track A comes on at frame 20 and track B at frame 35), but I'd like them to flicker/blink on for about three frames. What I want to know is, is it possible to assign a Noise Float Controller that only operates over a fraction of the four second shot (for eg. frames 20-24) (frames 0-20 the light Multiplier will be 0, after frame 24 the light Multiplier will be 1000). As far as I can see the Noise Float Controller works over the entire active time segment...which seems pretty obvious from the 'Float' part. Is there another controller I can use, or do you recommend that I manually animate each frame seeing as though there are so few?

 

Hope that makes sense!

 

Thanks a mil,

Terri

I would personally just render them out at a very low intensity with a light select render element and then do all the light animation in post production. You can tweak it in real time and when the client wants changes to the speed/intensity you can update it without re rendering.
