I was watching a scene where the guy was always just a little bit off center. I thought it must be hard to tell if you are perfectly centered when laying under the camera.
If there was a infrared light that came shining straight down from the middle of the camera, like a laser level light. Then you could see it from your chest all the way to your dick. Have the light going right down the middle of your dick, perfect.
Is there such a light invisible to VR cameras?
