Cinema4D vertex animation

Hi! I have skirt animation (from cinema4D) and I have vertex (edges) animation there. I'm not sure that using bones will be effective for the skirt movement. You can present t$$anonymous$$s animation like a Marilyn Monroe' flying skirt. Can you help me, how I can import that animation to Unity? I found the answers in t$$anonymous$$s forum, but that answers are too old. Thanks a lot!
