How do I set Texture Paths for Command Line Rendering?

1. Open the interface version of C4D, and make sure the texture path is set properly in your preferences. 
2. In the preferences window, click the 'Preferences Folder...' button.
3. Copy the folder called 'prefs'.
4. Move up one folder to the MAXON folder. Navigate to the preferences folder of the version of C4D you're using with the '_x' on the end.
5. Paste the 'prefs' folder. (Overwrite the folder here if it already exists.)

NOTE: As odd as it seems, this is Maxon's official method for setting texture paths for command line rendering. This workflow isn't tied specifically to how Greyscalegorilla products work.
