Blizzard animator David Gibson (@) uploaded a timelapse recording of his Overwatch animation process. From the video description:
“Hi, this is a recording of my animation process for animating Mei’s “Frosty :)” Highlight Intro from Overwatch in Autodesk Maya. This video was originally made and presented as part of the Overwatch Exhibit in Blizzard’s Irvine Museum. I hope this video will be helpful to animation students or anyone that is interested in learning more about the computer animation process. Enjoy!”
UPDATE: David has added another one – this time for Doomfist.
