I've been searching for an answer forever, but I haven't found one. What options are there for lip sync/facial expressions in video games made with XNA? I have a few models for a game I'm building, and I would like to know if it would be better to set up an animation for every dialogue, but that would be very time-consuming and the whole collection of files would result in a massive-sized program.
I was thinking about an automated lip-sync system, but I wouldn't know where to start! Any thoughts?
