Pretty simple question which I've tried to accomplish for hours to no avail... can one emit particles from a Form shape in any way? I've tried using Layer emit in Particular, selecting the layer containing the Form shape, yet nothing happens... this seems like something which should work, if only I knew how...

You would have to precompose the layer with form.

I tried that, moving the form settings to a precomposed comp, and after making the precomposed layer 3D it still won't emit anything as far as I can see...

Sorry... edit to my last post; it worked now, but the particles aren't responding to the movements of the form layer. The form shape is moving from fractal noise, and what I'd want is the Particular particles to be 'thrown off' this shape as it moves, whereas now it's just a static field of particles being produced over the space occupied by the shape, if that makes sense...

Particular & Form won't work together like that as you probably have discovered. While they both can use and interact in AE's 3d space, they are both 2d effects and they don't have the ability to measure the distance a flowing form shape is from the camera, or what direction it is flowing. All Particular will see is a white alpha channel that indicates it should put particles at that location, it can not discern which way the particles should be moving based on the movements of another layer.

This is something you might be able to accomplish in a 3D modelling application like C4D, but not truly in AE.

Perhaps you could fake it with multiple form layers, using the same fractal patterns. The top layer would have a lot less particles and the fractal could displace them quite far in distance.
