• needs to set Playblast settings:
  • Show Current frame
  • Show Currrent focal length
  • Show Camera name
• could save out Maya file and playblast in specific folders to get access
• auto publish to shot grid once we have shots built there

Notes from animation:

• Correct aspect ratio
• Playblast whole frame range even if they've edited the timeline
• only display polygons
• Shot Code
• Animator Name
• Version/filename
• Pass dropdown (Blocking, Polish, each has 1,2,3,4)
