Positions in CC Particle World are proportional values. direct pickwhipping will never work. Something like this would:
It will still not align perfectly, though, since CCPW does not respect the comp camera, so fiddling with the Distance and FOv parameters will be required.
Thanks heaps, it doesn't work but I'll figure out something else!
> All I'm simply wondering is how to link the cc particle world producer position points to the position of a title I want the particles to follow. I tried pick whipping the producer position x to the title position and the following expression (on the position x of producer in cc particle world) was created:
This makes the particles disappear. <
I use PW often to track other layers. I do not use an expression, though, I just parent the emitter to the motion path or mask shape/position. I am most often outlining text objects or doing the ol' laser carving in combination with Shatter. in that case, I parent the Shatter force sphere to a null that is tracing the outline path and parent the PW emitter to the same null. Easy and direct and very cliché.
