So I have been struggling with particular on a separate thread and i cant get it working so here's a follow up question.
If i wanna suck a load of layers into a point in a spiral vacume motion as if looking down on the central point, how best would i do that, if i have around 60-80 layers (duplicates of 6 original layers)
This needs to be done WITHOUT particular as i just cant get it working right, i think it's my gfx card, but thats a separate discussion.
Please see my mock up showing the motion required.
Ideally i would have the option to have the layers be fixed in their own rotational axis.
If the movement towards the centre is fairly smooth, you could parent your layers to a null at the centre, which would rotate to give the circular motion, and then scale the null down to make the layers move in a spiral. If you want the child layers to stay upright and the same scale, you could add a couple of expressions to invert the rotation from the parent null, and compensate for the scaling down.
Alternatively, if you want the motion to look a bit more organic and random, you could look at the Newton script on aescripts.com - version 2 had a magnetism feature which could do what you want.

ShapeShifter AE can do that quite easily with no need for layer duplication. Just apply SSAE to each of the 6 layers, use Generator to multiply and offset your instances in a spiral and animate the position and scale.
