Hello, all. I’ve been working with my younger brother on a Blender project he hopes to display for Halloween; he has made a textured model of his own head in Blender, and is now trying to animate it. He has a lot of Blender experience, whereas I have just about none, but this is his first time working with animation in Blender. The plan is to animate the head model using motion capture videos of his face. We were supposed to be further on in the process by now but life got in the way.
We seem to have hit a wall in connecting the model to the motion capture video. The test video we have has been tracked quite nicely, and my brother has placed the head of a bone at each point where he wore a motion-capture dot. The bones aren’t connected to any sort of larger armature at this point, but he made one of them the driver for a shape key he made for raising an eyebrow, and we started trying to connect that bone to the corresponding track from the video using a bone constraint. The problem is that we’ve tried every kind of constraint available and none of them seem to result in the bone following the movement of the track. Some of them cause the bone to be relocated to the cursor, or to become much larger or rotated in different direction, but all of them result in a bone which does not move or transform at all as the tracks move.
We’ve looked at several tutorials but all of them seem to involve a much more complicated armature then we’ve got, and most of them are for older versions of Blender (we’re using the 2.71 release candidate, and my brother is not keen on updating in the middle of things).
Does anyone have an idea where we’re going wrong?
Edit: I’ve acquired permission to share the .blend file we were working on. We were last trying to use a bone constraint to connect the bone called brow.L.I to Track.003. I can’t seem to upload any attachments, so have a Dropbox link: https://dl.dropboxusercontent.com/u/107628868/ME16.blend
Edited again: Halloween’s gone by, but we’d still much appreciate advice on this issue.
