Pre update, no matter the vehicle, I could hold my mouse look key (c) in third perzon and zoom in and out by pressing z. Zoom being on a toggle.
After this update however, in ground vehicles, zoom only works via toggle when you’re not pressing mouselook, when in mouselook zoom has to be held.
In aircraft such as recon drones, aircraft, and helicopters, third person zoom ONLY works when not using mouselook, using the mouselook seems to completely override the zoom.
