Exported dangle animation of feather/hair looks different

Hello,

i added a dangle to a feather and hair and it works like charm in character animator. They swing back an forth when moving the characters body etc. but when i export my character animation as a PNG Sequence the "physics effects" are almost gone or do at least have very less impact. The feather and hair appear stiffer and they are not swinging that much.

Any ideas to solve this problem?

Thanks in advance,
