Have a look at the Face (or is it LipSync) behavior. There should be ‘Views’ or ‘Handles” (sorry, not at computer to look) which shows how the different visemes have bound to different layers. Check which layers it has successfully bound to.
Things to try - add a behavior per profile to make sure everything in that profile is picked up - some behaviors don’t find all matches (although I think this is less likely to be the problem in your case). That is what looking at views/handles will hopefully reveal.
I don’t think the swap set structure will affect what gets bound to, but the layer hierarchy can. E.g. if alternatives are nested in the wrong place it might miss them. A screen shot of the full rigging hierarchy expanded of all the layers in the Mouth area could help (Not just the swap sets). It sounds like you have swap sets under control - its just the viseme binding that is playing up?
Personally I normally have the normal and alternative mouth sets as siblings under a Head layer. Your structure was as bit different. Not wrong, but if you run out of other ideas what I personally do is:
- profile (a lie - I don’t use profiles! ;-)
- - Head
- - - Gobs (not using “Mouth” to avoid auto tagging ;-)
- - - - Normal Gob
- - - - - Normal Mouth
- - - - - - Surprised (some emotions go here)
- - - - - - Ah
- - - - - - Oooh etc
- - - - - Normal Shocked (other emotions are siblings to the normal mouth
- - - - - Normal Confused
- - - - Sad Gob
- - - - - Sad Mouth
- - - - - - Surprised
- - - - - - Ah
- - - - - - etc (visemes)
- - - - - Sad Shocked
That way I can have a swap set under Gobs based on expression (normal, the default, Sad, etc). Within each emotion I then have another swap set for standard vs non standard expressions. Under the standard expressions I put all the visemes.
I am not saying this is better than the video - just sharing what I normally do these days. Your hierarchy you said works but felt like alternatives were “different”. I just like standard structure that everything follows rather than having a different part of the hierarchy for “alternatives”.
