At first, english ist not my gutterspeak so please use simply and easy english :)
I want to let Particles (done by Particular) fly in a black room and they form in a text ("Jeremiah").
After that, a wave goes through the text (i know how this works :)) and the particles fly out again and the text disappears.i tried to create a text layer, a layer with particular and set emitter type to "layer".But the Particles just went out of the text without a form :(.I tried a little bit more with no good result.
Play with the Turbulence and Wind settings and animate their strengths. Do not use any Velocity on your emitter. If timed well, you will get very gentle wavy patterns. For the fly-in use the same technique and time-revers your composition.
