Andy Needham creates a simple workflow tool for the Phong Shader in Cinema 4D that sets its smoothing angle to a more workable 30 degrees.

Set Phong is a quick and dirty python script that will easily set the smoothing angle for any selected objects at once.

Default functionality Sets the phong angle for selected objects to 30 degrees

Andy notes that by defualt the script will set the smoothing angle to 30 degrees, however if you shift click the button, you are able to choose your own preferred smoothing angle. Check out the download for the Set Phong C4D Python Script here.
