Hello there!

Here's a stab at getting things working. The key idea being to use the path deform on the whole motion clip rather than a single frame of the animation. Unfortunately at the moment we need to perform a couple of additional steps to get this working properly
- first use a Motion Clip Extract to ‘unpack’ the geo
- Deform the unpacked animation sequence
- Use a Motion Clip Update with to write the new world space transforms back to the Motion Clip.

The reason we need these steps is that the motion clips evaluate using local transforms, which remain unaffected by the path deform.

Hope that helps!
Henry
