Wiggle expression to mimick a faulty street light?
Hello all,
I’ve got a scene set up with where I’ve got an street light that I want to make flicker and light light up the whole scene. I’ve put an expression on the are with the light that is affecting the opacity of the “light”. Then I have a black solid that has been masked to light the scene like I want that is linked to the previous light layer.
So the wiggle expression I am using on the “light” layer to drive opacity is: wiggle(5,75)
The expression I’m using on the black solid to simulate the lights going out over the whole scene is: 125-thisComp.layer(“Lightintense light flickr”).transform.opacity
sorry for crappy naming convention 😉
The problem is that the flickering ends up looking kind of like candle light. Also, it is non stop. I’d like the light to be okay for a second or two, then have some heavy flickering, then back to full… then to have that type of cycle keep repeating. Basically I just want to make a flickering lamp that doesn’t look like a flickering candle, and that doesn’t necessarily flicker every second of the composition. any ideas? I’m sure there’s some simple idea I’m missing. Any help would be most appreciated.
Thank!

To get control over the wiggling I like to link each wiggle parameter to a keyframed expression slider control (one for amplitude and one for frequency).
P.A.T.
