CS5.5 Update: Adobe After Effects CS5 Vi... > Chapter 12: Light
Chapter 12: Light
Light Falloff
Note
This subsection fits at the end of the “Source and Direction” section in Chapter 12 of Adobe After Effects CS5 Studio Techniques, just before the section entitled “Color Looks.”
Suppose you need to add or match natural light falloff. Versions of After Effects previous to CS5.5 have more or less been forced to fake it, using tricks such as multiplying a couple of linear gradients to get anything like realism. With 3D lighting, you were out of luck if you wanted falloff, and that is the big change this time around. If your scene contains 3D layers that are meant to be lit realistically, or even not entirely realistically but with some falloff that you control, After Effects lights now include a couple of options that will make, well, not a night and day difference but perhaps a bad night and good night difference.
