Try one of the random motion expressions on motionscript.com. They give much more realistic motion than wiggle since you have temporal randomness as well.

Jim,

I just emailed you a little sample.  Let me know if it's anywhere close.  Maybe that type effect, overlayed where you want it to appear, perhaps more subtle.

I plan to have a camera truck along several framed photos on a virtual tabletop, and give the impression they're lit by a fireplace, and casting dancing shadows on a virtual back wall and table top.

Jim,

If I may ask, just for testing, what type of object do you want the effect to flicker on?

I'm getting OK results by wiggling a Light with a salmon color.

POI: wiggle(20,30)
Position: wiggle(10,100)
Intensity: wiggle(10,10) Initial Value: 150%

Comp is 23.976 fps.  

But, it still looks a little too regular or cyclical.  I think if I added another wiggle to a wiggle, I might get something that looks more random.  Or, maybe wiggle the camera.

Anyway… I think I'm onto something.  Better ideas welcomed.

Hi Eric,

I don't want to create fire, I want to create the look that fire has on objects: the wiggly shadows and highlights.  I'm guessing I could wiggle the light position, point of interest and add in some fractal noise or use real fire video and projection mapping.  

I was just hoping not to have to re-invent the wheel in case somebody has already developed a working method that they'd share.

Thanks,
Jim

Hey Jim,

I've never seen a tutorial about fire making that is specific to using an AE light but if you just mean, building a fire that reacts to light, I've seen several.  Here's one that uses particles. http://www.youtube.com/watch?v=1z9ti_dGgQE

The guy in the video above also shows his fire in a separate link (under more on youtube) or here:  http://www.youtube.com/watch?v=WV_j0RvnXfk&feature=youtu.be&t=24s

So, I guess practical fire isn't an option, such as some of the Andrew Kramer stock fire stuff?  I know there are a couple of them that look just like a normal camp fire and are real of course.

Does anybody know of a tutorial or technique I can use to make an Ae light look like a campfire on layers that accept lights and shadows?
