我最終編寫了一個腳本。
我幾乎找不到可用的C.O.F.F.E.E.文檔如此繼續並安裝py4D。
該文檔非常好，論壇上的支持是驚人的。

work around
1. store first key for each track curve
2. set the first key value to 1 for the 1st track and 0 for the others
3. store the mesh vertices -> track name verts = []
4. after all track verts are stored, restore the original values
5. write the the curve keys for blender shape keys
