I have a good Morph animation, with eh lip sync working, but when i go to change the teeth, lip sync has stopped, even though the track is there, and I can see the various mouth shapes in the time line, but the actual characters mouth has stopped moving?
In composer mode, I can change the teeth. my only option seems to start again from scratch. which is quite a lot of work to redo.

Any steps to be able to make changes, and re-apply the audio?

Regards
Geoff
