Had many inquiries of just buying some mattes themselves, threw them up for $5 if you wish to save yourself some time with following tutorial or rendering. 20 mattes, tutorial/documentation, other bonus stuff.
Tutorial of how to create a tear transition with C4D and AE that I used in my demo reel this year. (vimeo.com/62999101)
Feel free to ask any questions here and Ill do my best to help.
