If you parent a camera to a null object and then animate the null the motion blur effect won't be calculated in the final render. The same thing will happed if you animate camera on a path/curve. I hope it's a bug because otherwise it's a big issue where there is a very limited functionality to camera use if you need motion blur to happen in camera.

Haven't tested in earlier version so don't know if it worked fine there. Doen't work as expected in 27.16 OctaneBlender build.

Ok, I did some more testing and I can say for sure now that parenting Camera to the Null object or another geometry will make camera loose its in camera motion blur effect. I could provide my scene file but I can't find a way to upload the scene here on the forum to share it.

Can confirm this is happening to me as well on v27.16 addon. As a workaround, you can use the "Child Of" constraint to get motion blur to work again. The method also works when following a path.

We'll fix this.
