Hi! Lyra uses its own custom CameraComponent: source here.
They clearly developed this before the first person rendering was ever an option and didn’t include some settings in the GetCameraView override that are necessary for this feature to work.
You can add these lines to the custom camera component and the first person rendering will work!
DesiredView.FirstPersonFOV = bEnableFirstPersonFieldOfView ? FirstPersonFieldOfView : DesiredView.FOV;
DesiredView.FirstPersonScale = bEnableFirstPersonScale ? FirstPersonScale : 1.0f;
DesiredView.bUseFirstPersonParameters = bEnableFirstPersonFieldOfView || bEnableFirstPersonScale;
You can reference the original function in the base camera component.
Hope this helps.
Cheers!
