if I parent a layer to a Null, I expect it to stay exactly in place, however, I just noticed this is not always the case with cameras, as you can see in this (less than 2 minutes long) video:
Does anybody have an explanation for this?
Steps to reproduce:
1) Create a comp with
2) set the X-rotation of the Null to 180 degrees.
3) parent and unparent the camera to the null. You will notice that the camera filps upside down when parenting it and flips back when unparenting.
If you use a one-node camera, rather than a two-node camera, you'll see it won't happen. It only happens with two-node cameras because it's a mathematical issue relating to the camera's Point Of Interest.
thank you for this explanation. I also found this thread mentioning the same:
Does anybody know the exact conditions causing the camera to flip?
I am developing a script to reposition cameras and it should work with arbitrary cameras. Currently I have the issue that from time to time cameras flip and I cannot predict it.
