Join Chris Meyer for an in-depth discussion in this video Idea corners 3: Wandering electric arcs, part of After Effects Apprentice 09: Expressions.
Let's open up our third comp, Idea3- Electric Arcs, and take a look at that one.…Again, I'll press 0 on the numeric keypad to RAM Preview, and this will take a…little while to calculate because we do have a few things going on.…You see these different lightning bolts seeming to search around the screen.…Question is, how do we do this?…Well, again, we used our friend the Wiggle expression, in junction with another effect.…You'll notice in my timeline I've got three lightning solids, all in Add mode.…Just like lens flares, the advanced lightning effect is something that generates light.…
Now, I prefer to put them on their own black layers so I've got more control…over how I blend their opacity and what blending mode I use.…I've also created a MASTER CONTROLLER, again, for Wiggle Amount and Wiggle Speed.…For the Advanced Lightning effect, I'll type EE for expressions.…I created what looks like a very long complex Wiggle expression, but…actually it's very simple.…Again, it's just Wiggle, how fast, and how much?…
