I did not get this when I downloaded after effects. Where is it / how do I get it. I have version 18.104.22.168
You can only open C4D lite from inside After Effects. Do that by going to the File menu and selecting New>Cinema 4D file or by importing a C4d file into the Project panel or placing it in the timeline and then choosing Edit Original or if the C4D file is in the timeline you check the Chinaware Plug-in in the Effects Control Panel and click on the Show button.
