  Camera Trailing Particle Stream

  Posted by Ryan Kehn on February 26, 2009 at 11:26 pm

  Hello all,

  I’m hoping someone has a tip that will help my headache go away.

  What I’m trying to achieve is to have my camera follow a stream of particles from behind. Easy enough. The catch is, I would like the particles to start behind the camera and enter into view after the motion of the camera has started. I don’t want to see the start of the stream (if that makes sense).

  Currently, i’m using the valueAtTime() tag on the null linked to the emitter to keep the stream ahead of the camera (since the camera was animated first, also with a null). I’m kind of stuck on how to get where I’d like to be. Let me know if my explanation doesn’t make sense.

  Thanks in advance for any tips!

  Ryan
