This boolean, bTakeCameraControlWhenPossessed, is meant to be available to stop pawns taking view target control of the camera when they are possessed. Here is the doc reference:
It is however missing from BP and from the C++ API and actually missing in the source, as it evident from looking through the engine code itself and getting compile errors trying to use it in an APawn derived class
Can we please get it back? I really want my game to not support my pawn taking the camera by default
Thank you very much!
