Based on the popular 3D Assistants Pro package, the EZ Assistants are a collection of six keyframe assistants that enable you to easily manipulate, animate and arrange layers in 3D space.
If you only occasionally use AE's 3D space, the EZ version provides, well, an easy way of creating complex animations. And you don't have to dig through our manual to figure out all the options, which is great if you're not familiar with AE's 3D space to begin with.
Overall, the EZ version will provide enough functionality for hobbyist or intermediate users to create some great work in AE's 3D space, quickly and easily. It offers an affordable and intuitive way to use 3D within After Effects.
