[Chris Smith] “That’s it in a nutshell.”
Hey, stop reverse-engineering our stuff!! 🙂
Hehe, that’s a pretty good description. If you don’t want to get into Maya you can do similar things with Trapcode Particular inside AE: Use a Light Emitter and set “Velocity” and “Velcity from Motion” to 0 and you will be able to “paint” by keyframing the 3D position (3D motion path) of the light. Now, the “Size over Life” curve can be used to create tapering (and other exciting shapes). Note: keyframing the 3D motion path works so-so; you need to hit “purge” every now and then to get accurate rendering.
