Particular problems with trapcode particular

Help.

I'm trying to recreate that whole light trail effect we've seen around using a particular. I saw it first in a video for citizens that koxvold did.

I have tracked the object I want to add the trail to and then applyed the track to the particular layer.

The problem I am having is that the trail's emitter is placed right at the edge of the frame and once I add some wind physics to it the particles blow out of frame.

I've tried making a bigger layer but the emmiter still starts near the edge and I just have the same problem....

I've toggeled every single thing in the particular menues to reposisition the emitter but it doesn't move.

Any ideas?

i don't know if this is it or not but i would apply the tracking data to a null and then parent the layer you want tracked to the null.
 
I will try that right now. Not sure about "parenting" but I bet I'll figure that out.

Hope it works and thanks for the tip.

Man. I suck in after effects.

Now I got my thing all screwy.

The frame with the particles is now tracking with the motion track. It's crazy.

I need the frame to stay comp sized and in place and then track the emitter to the motion track.

Ideas?
 
That's the thing. I can't figure how to move the emmitter. It's like it's locked in spot.
 
The first section of the effect settings in Particular is "emitter". You'll notice that there is "Position XY" and then Z below that.

You "should" be able to copy and paste your XY tracking data to this Position, as they are the same kind of property. Just make sure that your layer sizes between the image being tracked (the video) and the particular solid are the same dimensions.
 
Steve, perfect!!!

Thanks.

I't sort of working now but when I apply wind the whole thing moves and no longer emmits from the track that took forever to make seeing as the built in tracker is a pathetic joke.

I'm about ready to ditch this project!!!!

And I'm starting to hate After effects.

Thanks for the help everyone.
 
okay it's working a bit better now. just needed to swear at the screen for about 25 mins.

thanks again for all the help guys!!!
