The process of polishing is all about adding the subtle details into your animation to add to the art of imperfection and help push your shot from good to great!
Notice that before polish even starts he states that he makes sure that he has a solid foundation to work with. This solid foundation is the blocking and splining of the shot.
Complete the splining and polishing phase of your heavy box lift animation and export a playblast once complete.
If you have to export .avi playblast from maya then Follow these tutorials to convert to mp4 for submission.
Submit your MP4 file to Assignment 2 on UNM Canvas before midnight next Sunday.
