Lead Animation Faculty over at
AI of Salt Lake and
Head of Long Winter Studios,
Andy Conroy just released a tutorial over at
Digital Tutors that is all about
Smear Frames!
I learned a ton about Smears from Andy while we worked together and have been able to carry that with me through my career. I highly recommend you check it out even if you think you know a bunch alreay cause it's always worth gaining some more knowledge.
Enjoy!
