One of the things I demonstrated in at the LA presentation was the use of normal maps in After Effects to simulate realistic refraction and reflections. The technique is very fast and very powerful using a free plug-in called Normality.
Stefan, the developer even worked in a few solutions based on some feedback I sent over. He really built a great tool, in fact there are so many possibilities that I have been working very hard developing this new tutorial to demonstrate several examples of what is possible.
SIDE NOTE: I Just finished the new build of QuickMatte for Windows and Mac so I’m going to try and get that out shortly.
