After I published the 'Digital Makeup' video by Sebastian König this week, people were quick to point out this approach didn't work for expressions. Well, no more - Sebastian figured it out.
Another test of facial motion capture with Blender. I didn't tweak a lot on material or lighting, so that could be improved. But the basic concept works, I think, even though it is a rather tedious workflow. But it's quite good and can make very advanced stuff possible.
There is a little bit of sliding, which would have to be improved too, either with more markers, or by adding some manual shape keys.
But as a start I think this technique is really helpful.
That head tracking device made tracking a LOT easier, because it adds a lot of perspective, but of course this would have to be painted out in a real production. Or hidden with hair/helmet/horns/wig or whatever. :)
All in all this took me 4 hours.
