Thank you! This may well be simple finger-trouble / snow-blindness on my part, but here’s SGs:
FBX: it’s an animation imported via Terabilis from Mixamo and works in 5.4 (my interest is primarily in facial animation at this stage, I’m trying to see if there are any options for blending livelink face capture with the new lip-synch tool, which seems to work pretty well for dialogue but of course leaves the upper part of the face seeming somewhat uninhabited). I’ll also look at your suggestions re: resetting, as this feels as though it’s in the ‘should just work’ category of problem. Thanks again!
