After Effects includes a free installation of Cinema 4D Lite - part of Maxon’s 3D software package. To use it, you are required to sign up for a free MyMaxon account. Maxon does not share your information with anyone, but you can expect emails about how to get the most out of C4D Lite, and expand your 3D capabilities. If you do not wish to receive these emails, you can opt out at any time. When creating your login, you can choose to use Lite or install a 14-day trial of the full version of Cinema 4D. Once that trial ends, your version of Cinema 4D reverts to Cinema 4D Lite with no time limitations. If you are an After Effects user and wish to upgrade to the paid version of C4D later, you can check out the special packages offered by Maxon.
