I seem unable to export a camera with the Alembic ROP.

I just get the error:
Invalid index provided to getTimeSampling

I'm pretty sure this is to do with the setup I am using. I have a point which has been baked out with N and up vectors. I've then got a rivet which is attached to this point and the camera is parented under the rivet.

Is there a way to get this to export correctly. I've attached the file.

chops. great for getting clean exports from heinous rigs.

Yep. That's working now. I need to work on my chop skills :?. Thanks cpb.
