I’ve gotten a few questions about FreeForm, which is an effect that was bundled with After Effects CS5 and After Effects CS5.5 to distort 2D layers in 3D space.
No, FreeForm is not included in After Effects CS6.
Yes, you can still use FreeForm in After Effects CS6, though not the version that was bundled with After Effects CS5 and CS5.5; Mettle needed to make some changes to the plug-in for After Effects CS6. In After Effects CS6, you can use the new (and faster) version of FreeForm or an even more feature-rich version, FreeForm Pro, both of which you can get from the Mettle website.
As After Effects adds more native 3D features, our plug-in partners like Zaxwerks, Mettle, and Trapcode will continue to provide additional features through their products, allowing you to go beyond what is possible with the standard After Effects package. Zax Dow of Zaxwerks makes that point very well in this interview on Motionworks.
