Every Nth Frame—The number of frames used by Notify Progress. Default=1.
Notify Failures—Sends an email notification only if something occurs to prevent the completion of a rendering. Default=on.
Notify Completion—Sends an email notification when a rendering job is complete. Default=on.
Send Email—Notifies via email.
Include Summary—Includes a summary of the network rendering progress with the notification email. Available only when Send Email is turned on.
From—Enter the email address of the person who initiates the rendering job.
To—Enter the email address of the person who needs to know the rendering status.
SMTP Server—Enter the numeric IP address of the system you use as a mail server.
