Stereo 3D Toolkit from aescripts is a Script more than a 3D camera. It is a set of tools that enable you to create complex stereoscopic compositions inside of after effects. 3D Toolkit uses true left and right channels instead of collapse transformations. Because of this, it is compatible with all 3D effects and plug-ins that utilize composition cameras. Effects like Particular, Form and Plexus come through with true stereo 3D depth.
It designed to make managing complex hierarchies simple. The tools enable you to work on the left channel and automatically update the right channel. Nested pre-comps are given embedded cameras that are locked to the master system, so all of the pieces in your hierarchy stay in perfect sync no matter how complex it gets.
