Connect pemitter center to tracker path?

PostSun Nov 19, 2017 3:28 am

I have a panning shot that follows a moving vehicle. I've got a tracker on a part of the vehicle. I want to connect my particle emitter center to the tracker path, but I can't figure out how to do it. Thanks for any tips!

Hey,
You have to select your emitter > go to the properties panel on the right side and right click the center to attach it to the path.
If you have a merge in your tree, you may do it with the merge...

pEmitter's a little different than most tools because it has separate controls for X,Y, and Z rather than a Center control, even when the particle system is in 2d mode.

In the pEmitter's Region tab, right-click X Offset and choose Connect To > Tracker1 > Tracker 1: Offset X Position (3D Space)

Do the same for Y Offset. The pEmitter will not immediately update, but if you step forward or backward one frame, it will snap to the right place. It will also appear to have the wrong numbers—that's because it's projecting screen space into 3d world space, but as you can see from this screenshot, the pEmitter's circular region is in the right spot according to the Tracker's Center.
