I created an Ocean simulation, with an object "floating" on it.

https://www.youtube.com/watch?v=mZUkHyDC1lk&feature=youtu.be

Now I need to export this to Nuke, so I need to convert the movement of the floating object to 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?

    $\begingroup$ 90% of what you wrote is irrelevant. $\endgroup$ – someonewithpc May 2 '15 at 20:56
  • $\begingroup$ @someonewithpc Yes, but I added a description of "my plan", and highlight it in the text as a separate part. I did it because my main goal - to get an object that moves and turns in the same way as a floating object (no matter what the object is), and perhaps there are other ways to solve this problem except the way in which I asked about. So I left this additional information in case someone offers another way. $\endgroup$ – Rumata May 2 '15 at 21:08
  • $\begingroup$ Then that's a different question and should be asked separately $\endgroup$ – someonewithpc May 2 '15 at 21:09
  • $\begingroup$ @someonewithpc Sorry if I confused you. In my scene object floating in the water, so it moves a little bit and turns. If I animate it manually, I would have used a key animation - from key to key, from phase to phase. But there is another way animation works - floating object receives information about how to move by analyzing the surface of the ocean, (here is a tutorial youtube.com/watch?v=11F1NRpqrzY). But I can't export this animation to Maya or Nuke - because it depends on the "ocean modifier" which does not exist in Maya and Nuke. $\endgroup$ – Rumata May 2 '15 at 21:16
  • $\begingroup$ 1) How to do it? If I click apply, the ocean freezes. 2) Anyway animation of the floating object will be calculated using the "copy location" and "Copy rotation" (constraints menu), I think in Maya and Nuke these tools don't exist. $\endgroup$ – Rumata May 2 '15 at 21:24

Yes, it is possible! :) You can use the "Bake action"!

If you have an ocean, and an object that "floats" on the surface of the ocean using the method, described in this tutorial (https://www.youtube.com/watch?v=11F1NRpqrzY)

enter image description here

do the following:

1) Select a floating object

2) Press T and in the left pane, select the tab "Animation"

3) Press Bake Action, select the frame range and check "clear constraints"

enter image description here

4) Voila! You will see a lot of yellow strips in the timeline - the key frames of animation.

enter image description here

Now, if you delete the ocean and sphere by which you drew in the dynamic Paint mode, floating object will continue to move as before.

  • $\begingroup$ Could you add some more detail, i.e. what needs to be selected, and an example of the result? $\endgroup$ – VRM May 3 '15 at 11:55
  • $\begingroup$ @NoviceInDisguise Sure, done! :) $\endgroup$ – Rumata May 3 '15 at 14:09
