Using the toComp Expression
Note, while I fix my stupid Flash playback issues, go directly to the QuickTime movie here.

This is an old tip that I’ve never formally published as a tutorial. It demonstrates a couple tips on how useful the “toComp” expression with Knoll Light Factory, Shine and more.

Creating a “Draft Switch” for Form
When working with high particle counts in Trapcode Form, the only thing that will speed things up is a lower number of particles. Creating an Expression Checkbox as an “on-off” switch for this is a efficient way to manage render times when working with Form. Here is the expression used:
s = effect("Checkbox Control")("Checkbox");
if (s==1) value/4 else value
Make sure to add a checkbox control from the expression control effects.

Title 3D Invigorator + Video Rock
This is a tutorial showing some trick I’ve been using lately, creating an edge glow effect on 3D surfaces. I first used this on some Cinema 4D renders on the TV Land spot here: graymachine.com/2009/10/tv-land-prime-feels-good/ and really liked the effect.
In the example here, I am using 3D Invigorator, something more people are probably familiar with.
