I have a question I wonder if anyone could kindly help me with? I'm really stuck on it at the moment.
What I'm trying to do is take one object and multiple it hundreds of times and have them cascade down the screen, so it looks like it fills the whole screen with multiples of this one object - from the bottom to the top of the screen.
Does that makes sense??
Is there an effect I can use to achieve this? I've had a look, but I'm a bit new to this and it's not jumping out at me.
Any help or ideas would be really appreciated!
Thanks so much
It sounds as if a particle system is what you want to use. There are a few which come with AE (Particle World, etc.), and the king of the hill, Particular.
I can't remember whether the included ones have the ability to pile up on an alpha channel, but that is what you want to do. Where the alpha ends at the bottom of the screen, is where you would want the particles to start accumulating. In Particular, you can even set them to bounce and settle. Here's some info on Particle Playground: http://help.adobe.com/en_US/aftereffects/cs/using/WS3878526689cb91655866c11...
Newton 2 also has that capability, with actual physics capabilities - gravity, weight, and a number of other factors, but it might be overkill, although I also think it might cost less than Particular.
Thanks Joe, really appreciate your help.
I used particular and it's created the sort of effect I was looking for. Still can't work out how I'd get them all to settle on the bottom of the screen, but they're spreading out to fill the screen, which will work for now.
Depending on how you want the particles to animate you can use Plane Space from Red Giant also.
Another good option is to use one layer with the Generator from the Mettle plugins - either FreeForm Pro or ShapeShifter AE. You can create multiple instances and then animate them to fill the screen with a bit of tweaking.
It could on a layer with alpha, but the animation of the image filling the screen would be pretty boring. However this opens up a new posibility: use Motion Tile to create a perfect grid from one layer and then Card Dance to animate the tiles.
