Making Particular Follow a Null Whilst Rotating
OK, I’m tearing my hair out here on what is most probably the simplest technique.
It’s basically this:
I create a comp 500×500
Then create a NULL which automatically centres.
I move the anchor point and then create a solid and place in Particular.What I’m trying to achieve is making the Position X,Y of the Particles FOLLOW the NULL’s position. However if I try to rotate the NULL, it goes around the Anchor point fine but the position doesn’t change. Therefore if I parent the Position X,Y of particular, it doesn’t move as it’s still seeing the original (and static) Position point of the NULL.
How can I make Particular follow a NULL whilst rotating it in a circle, rather like light streaks captured when someone does a circular motion with a firework sparkler in the dark if you see what I mean.
Phew.
Thanks in advance for any advice.

I think I understand the question…
Try making the Particular with a Light Emitter, parent the Light to a 3D Null in the centre of the comp, then just rotate the Null on the Z-axis. A lot easier than trying to do it with expressions.

I’m not sure I completely understand, but you can just use a light called “Emitter” that is parented to a rotating null. There are more complicated ways using expressions.

Yup, I managed to figure the problem out as you mentioned by using an emitter..Now it’s working fine. 🙂
Thanks for the help, much appreciated.

A Particular Layer is inherently a 2D layer BUT it works within a 3D space which is essentially within its own 3D space. Parenting a Particular Layer to another layer will inadvertently lead to undesired results.
To link a Particular Layer to an AE Layer, your best option is to use a Light Layer – as others have opined in this thread.
