Issue with importing animation from Cinema 4D.

Hi all!

I'm just starting with Unity and let me say how excited I am to get further. I've encountered my first issue.

I'm doing a couple of animations in C4D, simple one, follow spline and deformer. Both import well, I can see them and play them in the preview inside Unity. But for some reasons when I apply them to the object inside Unity (which shouldn't be needed honestly), the animation doesn't play inside the tool nor in the app.

Any idea what could be the issue?

PS: We've tried to follow these exact steps, still not working. https://www.youtube.com/watch?v=BNNesTZrmJg

Thank you!!
