I have changed the way mesh changes are detected in the new release of the plugin. Could you pls check if that addresses the above problem, and if not, let me know.There seems to be a same issues of checking, when you move an instance (only when create a multiples instances) :
1) load a character and put hair (put it as child under character), wardrobe (put it as child under character)
2) make an instance of the character (with hair and wardrobe). Render OK. move it : render OK
3) make multiple instances of the same character (using Create/New Node Instances), move one of these instances, and render : Oh hair and wardrobe don't move with the character.
4) Need to rebuild the scene to render correctly.
