I wish I could share but i’ve been told it’s not yet shareable sadly - I’m going to try to secure some different assets that behave in the same way - I realize how useful being able to share a problem in a fiddle/codepen is.
My best guess is that it’s something to do with the body model only animating the upper torso and not the lower part since the shirt works as expected and the pants do not.
The only solution I am poking at it to see if I can record the time, stop it, add to the group then restart the animation but starting it from the saved time… not doing the right thing currently but there might be something there.
