Before posting, I've already tried parenting the camera to the Character mesh head and setting controller yaw, that didn't work, in fact it invalidated my blueprint to set my Mouse X and Y for the pitch and yaw that allowed me to move my camera in the first place. So I need a different method to make my character follow the way my camera is facing whenever I rotate, otherwise when I turn around I just face my Character.
NOTE: I've assumed you've set up your camera so it can freely rotate around the character mesh and you want the character to rotate with it.
Although costly, the quickest way to achieve what you're after would be to use the Tick function inside your character blueprint.
On tick, get the rotation of the camera then set the rotation of the mesh to the same.
You might need to make an adjustment in your calculations, making one of the axes -180° to get the mesh to point the right way but once you've got it, it should work fine.
