I'd like to create some text (no problem)
Convert to Masks using Layer > Auto Trace (or perhaps Create Masks from Text)
Then have Trapcode Particular create light streaks that "write" the text along the mask path(s)
My trouble is how to get a null object or perhaps an Emitter light to animate along the mask paths...I understand the light streaks, I just need the light to follow the text path created by the masks...
Thank you! Hopefully an easy one but couldn't find it here.
This is pretty simple. Just select your mask path and copy it by hitting control-c. Then, select the position parameter of your null object or light and paste it by hitting control-v. That should do it. Note, the keys will rove over time, meaning you can slow down or speed up the animation by moving the end keyframes. The middle keyframes will automatically space out accordingly.
