I was wondering if anyone could explain, or if they know a tutorial that covers an effect that is in the first 10 seconds of this video https://vimeo.com/58449984 I know that you use an emitter with spheres but how do you get them to only appear through the object (the circle)
Is it possible that they exported the emitter with the spheres to after effects in 2d somehow? and then just used track matte with a video of the bridge as the parent?
If so how can you export the emitter it so that it acts 2d? I am looking to do this with lines instead of spheres also? does anyone know a good way to randomly emit lines untill they become solid?
