My cinema4d files render in After effects in software mode only. Exporting the finished movie has the grid floor even when the grid is turned off in Cinema4d Lite. Using the standard render views (draft and final) only display black.
Nobody can tell you anything without proper system info or other technical details like exact versions or render settings in the C4D file.
After Effects 18.104.22.168 on Mac
I've changed settings and tweaked TCP communications in firewall settings.
