The best “hack” that I know of to handle this looks something like this:
- Add an “empty” node to your scene.
- Parent your mesh to that empty node
- Have the empty node follow the path
- Bake the animation to the “empty” node.
- Delete the path
- Export mesh (with “empty” node parent)
Essentially what that does is “transfer” the animation from the path to the empty node which can be exported normally.
Hope that helps a bit!
