No zooming when aiming in 1st person, even with a scope?

Can't find a setting for this in the INIs or anything, am I missing something?

If you are using camera mode, it is possible because camera mode is not completely finished yet.
Try to disable the camera mode.

The only things I have enabled outside the Main section of the INI are the water shader, AO, bloom, sharpening, SMAA and underwater fx. Also disabled the mod controlling FOV. I assumed it must be something to do with the "immersive camera" listed in the features? I also don't get any zoom when using VATS.

Is NVR the only mod you are running? If not, it could be the fault of a different mod--I'm not saying it is, however.

I'm running quite a few mods, but disabling NVR completely fixes the problem and I don't see it being a conflict with anything else I have.

Set fov to 0.0 and disable the camera mode. There is nothing else where NVR can interfere with the aiming.

Had already done that, but I ended up just switching to an older version, no problems with it.

For anyone still using newer versions, after turning off camera mode and aiming/iron sights are still broken, try commenting out all of camera mode's related settings by putting a semicolon at the start of the lines they're on. Did the trick for me.
