Sync Flare with 3D null object
Hi guys, Im using AE and I have a null object (where my camera look at), and I want to add a Flare to that point. What I did is to add a new solid, applied a flare, and using screen mode to blend the layer, it transfers really good to the comp, but! I cannot sync the flare position (2D) with the null object…
is there a simple way to do it?
I thougt about using some tracking but i dont know if it will work fine.
Any advices will be really appreciated! -

You can tie them together with an expression.
Name your null object “Flare_Source”, make sure 3D is enabled for it.
Now after you apply the flare effect to a new layer, Add this expression to the flare center attribute:
thisComp.layer(“Flare_Source”).toComp([0,0,0]);

Hi Andy, thanks for the reply!
Im trying to tie both objects but I got an error message:
“Unterminated string constrant Expression disabled.”
The software disables the link… is it right the expression or maybe Im doing something wrong… -
Seems to be working for me and im not Java savey enough to determine what the error is referring to.
Here is an after effects project file where I linked a null to the flare using the expression. It’s created in CS4 that should open in CS4 or or CS5.
