If you download the python fbx SDK, it comes with a bunch of examples: https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk-2019-0 In particular, "samples/ImportScene" has a very detailed example of how to read the fbx scene, look up all the objects, read the mesh data, and reach the animated properties: $ python ./fbx2019/samples/ImportScene/ImportScene.py ./ball.fbx File: ./ball.fbx ... Time Mode: Frames 30 Drop Timeline default timespan: Start: 1* Stop : 40* ... Mesh Name: ball Control Points ...
