In the latest update, The Face Mirror has been changed to use the orthographic projection camera.

But seriously, we see the world through perspective projection.

So the current face that face mirror shows is not the right way for us to see.

I don't think it's bad to use the orthographic camera for the face mirror, but it should be possible to switch the camera perspective.

With the update the other day, the camera used for Face Mirror was changed to parallel projection.

However, usually the world we see is represented by perspective projection.

Therefore, the face that can be seen with the current Face Mirror cannot be said to be the correct way to see it originally.

I don't think there's a problem with using a parallel projection camera for Face Mirror, but you should prepare an option to switch to a perspective projection camera.
