I bought it in advance of me using it in the main because the 50% offer ends today.
Good call. You should be happy with the ability to set tangents for key-frame transitions.
So, I think I grasp your technique, you attach the camera to a block? is that to simplify the controls of the camera?
I could have controlled the camera itself with the same technique. But the camera is small, gray and hard to see. That is why I did attach it to something bigger, blighter and controllable. ;)
