Question Facial morphs twitching when combining different morphs + lip_sync

[pinosante]

Hi everyone,

I don't know if any of you have this same issue, but when I have a Person who is talking using the lip_sync pluging which allows for lip movement, I notice that the emotion-animations I made for the face, randomly do some twitching when playing. Not all the time, but some of the time. I suspect this is the combination of using different morphs + lip_sync plugin. Does anyone have a solution or even know what I'm talking about?

to me it sounds like a conflict on the same morphs, maybe your animation is trying to update something with a value and the lipsync updates it with another value so it jumps quickly between the two. I'd turn off animations and do lipsync alone, select pose morphs & active only and see which morphs get altered. then cross reference to what the animation alters

Thanks, this helped. In the end I also found that I had both a Mouth Smile + a Mouth Smile Right in the same animation, with different number settings. So that also added some twitching.

nice! if you're doing the animations through code I recommend Mathf.SmoothStep, it makes the interpolation more natural with slow down towards the start & end. took me a while to find it and did all kinds of weird stuff to keep animations from being too linear when there was already that function to help

I just use TimeLine for my animations, I didn't even consider using code for that. Interesting. But I'm only okay in python, not in C-Sharp. And I haven't felt the need (yet) to dig into C-Sharp for my VAM needs.
