I never encounter this problem before as I was using alembics all the time.
However if I switch to bones and morph target driven skeleton meshs, the eyelid seems to record the silhouette when it was open.
I am using 4.26.2 and turned on 1. forced recompute tangents, 2. skincashe and 3. GPU morph target as the old thread suggested . But no luck.
Any help will be much appreciated.
