Converting movement animation of the floating object into animation keys (for export)

I created in Blender sea, and placed in the sea floating object.

I want to put a dog in this scene, so that the dog is sitting on this floating object.

I need to add a dog to the scene using Nuke, not Blender.

***My plan is:

In my case, there will be less bugs, if I export from Blender to Nuke through Maya.

So i need to export to Nuke only camera and a floating object.

In Nuke, I’ll create a three-dimensional plane with the image of a dog, and I’ll make it move, repeating the movement of the floating object. And I have to use the camera, exported from Blender.

Then I will combine render from Nuke and render from Blender. That is the plan.


So I need to export the scene to Maya, and then export it from Maya to Nuke.

My main goal - to export the camera and an object (no matter what), repeating the rotation and the movement of my floating object.(without the ocean, light, and all other objects)

But the movement of the floating object has no animation keys - floating object repeats location and rotation of the ocean, in the area that I’m drawing using invisible object (dinamic paint).

Can I somehow convert movement animation of the floating object into animation keys?
