help please with camera viewport

Hi - been messing with the car tutorial created a rearview mirror cam - also placed the main camera inside the car for a FP view. I wrote a script for the main camera to rotate right left so the player can see the l/r side mirrors. It almost all works great except… When I rotate the main camera to look right left obviously the scene view changed but the rearview cam viewport moves in step with the main cam rotation. Been banging my head to figure out a way for this not to happen. Both the rear view cam and main cam are children of the car. Any help would be greatly appreciated.

No idea without seeing the code… best I can say is that either you have something incorrectly/inappropriately parented, or you have code correcting for a parent transform you don’t have…
