    I am currently working on a project which involves particle system that morphs its shape to create different figures. It is somewhat similar to the school of fish showing the directions on Pixar’s “Finding Nemo”, however it does not require 3D.

    Using text on path with a wiggly selector modifying the position I am able to scatter the text elements around, reshape the mask and then bring the elemants back to make a new shape… howevever in this project the particle elements have to be graphic sprites, not the text.

    Is there any way to substitute text with graphics? Or is there perhaps a 3rd party plugin that could give me enough control over particles to reshape the system?

    Any help appreciated, needless to say, as usual in the industry it is rather urgent.

    Um, I’d say it depends on how you built the thing from the beginning.

    My inital idea would be to precomp your letters animating, or placeholders to later put in the graphics, then use trapcode particular with the comp as your source particle.

    That way you can go and open the precomp later and put in what you need.

    Not quite sure if that was what you were asking, but hope things go well/

    As far as 3rd party effects, Trapcode’s Particular will allow you to map other layers as sprites to the particles.

    Yes but that would still call for tons of keyframing, I was thinking of a system of around 400 cornflakes…

    Particular is great but it lacks enough dynamics control, you can just doi a simple bounce of the layer or stic to it, but it is impossible to make them fly between different containers.

    I guess Maya would be the way to go in this case.

    Maya would obviously work. However Maya’s sprites have to use the hardware renderer which isn’t always the greatest results. I would map your corn flake image onto a plane and have the planes constrain toward camera. That way you can render out with the software renderer.

    In Maya. You can have the particles emit from two different curves. and change the particles goal over time to morph from one to the other.
