To include a pass for the complete image, enable this option and on Cinema 4D’s Render Settings / Multi-Pass tab, click the Channels button and choose RGBA Image from the menu that appears.
Enable these options to include a depth pass for just the lines.
Enable these options to include an alpha pass for just the lines.
You can also split the line types into separate passes. To do this, enable the Split Line Types option and enable the option for each line type that you want to include as a separate pass.
This gives you separate passes for visible and hidden lines.
