We are not using the tech, haven't used it and I'm not sure if we will. You get a very accurate surface, no question about it, but that also means that it's most suited for a 1:1 recreation of the talent. It's also a lot harder to modify the performance unless you write some complex tools to manipulate the data. For example it's common to change character heights, timings, eye directions etc. and that's a bit harder if you are not working with elemental expressions.
Still, this data can also be processed in many different ways and can get more accurate results than just using a face cam. Anyway I kinda have to go now but can back to this later...
