Within each environment is a list of jobs that contains all the segments for your animated sequence. If you are creating a weekly television series called The Show, you could name your job show_ep_06 (the_show would be the name of your environment).
If each episode is composed of 100 animated shots, each job would contain 100 scenes.
IMPORTANT You cannot archive a job by deleting it. To archive a job, export first and save it to a secure location to be stored permanently.
