Maybe something like this…I’m not sure if I know what you mean

probability = 12;//some number from 0-100
seedRandom(index, true);
shouldWiggle = random(0, 100);
if( shouldWiggle < probability ) wiggle(2,7) else value I don't hava AE at this machine but I think that should do the trick. ~Colin

What particle system are you using?…If you are using Particular I don’t *think* this is possible, however I can’t speak for other particle systems like Particle Playground. You can do things like this fairly easily in Maya, however.

Sorry about that, for some reason I didn’t see Yikesmikes’ post…but anyway if you were going to go the expression route I would use “ease” interpolation. The expression would look something like this:

ease(thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”), 0,20,0,5)

AE does not natively have 3d reflections, if you want them try Discreet Combustion. However, In many cases you can fake them in AE. Anyway how do you expect these reflections to work? If you have a picture of a Ferrari and flat text how would the reflection look? It wouldn’t look like the reflection is actually on the car itself, it would look like the reflection in on a picture of the car floating in 3d space.
If you just want a picture of a Ferrari with some floating text in the air that appears to reflect on the Ferrari I think you could fake this using AE or Photoshop.

I’m pretty sure Particular has a blue spark preset or something like that..

Shift + click to select a single point on a mask…highlight the mask in the timeline then press Ctrl + t to bring up the free transform box so you can scale/rotate/move the mask as a whole.

x=thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
mult = 1;
if( x > 50 ){
mult = 20;
}
thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”) * mult;

Enjoy.

Have you tried choking the matte and eliminating the green stroke all together? If not, see if the Matte Choker or Simple Choker effects do the trick.
