Baking a Null Object

Recommended Posts


Yeah, I thought that too, but the null is actually under a motion camera (OP is a client of mine, and asked by email), so that doesn't do it here.

But I don't know what does - any ideas AB ?

  • Yeah, sorry. Forgot to mention the fact that the null is paired to a motion camera (to grab the groovy motion from it) but having it attached to the motion camera limits what I can then do with it. So there's no keyframes on the null at all. 

    I've found a workaround using CD Constraints for this current project, but baking an objects motion that doesn't have keyframes has been a question for me for a while. I thought maybe some sort of dynamics cache might do the trick seeing as dynamics also don't have keyframes generally, but found nothing so far...

    Not sure of your specific project, but drag the actual Motion Camera to the Timeline, then try Functions>Bake Objects... Then use the duplicated camera effectively as the Null. That should work.

    Just to add to the above, if you for some reason must have an actual Null and the duplicate camera won't do the trick:

     

    Do the same thing by dragging the Motion Camera to the timeline panel and Functions>Bake Objects... to get the keyframes initially, add a Null, then go into Automatic Mode in Timeline panel Alt(Opt)+A or View>Automatic Mode and then highlight the Position & Rotation fields on the left under the duplicated camera with the keyframes and Ctrl(Cmd)+Drag them to the Null and the keyframes from the camera will be copied that way to the Null.
