That title is probably a bit confusing so lemme try to explain what I mean:
Let's say I have two objects: Object A and Object B, and two cameras: Camera A and Camera B.
I want the position and rotation of Camera B relative to Object B to be the same as the position and rotation of Camera A relative to Object A.
I've tried experimenting with different combinations of drivers and constraints, but I wasn't able to get it to work. If anyone could help me out it would be greatly appreciated!
