shouldn’t it be infinite?
In practice it cannot be. There is no perfect mirror so the light will attenuate. My V-Ray attempt might attenuate too fast but the practical examples I have seen do fade into darkness. Also, the camera isn’t quite in the eye of the blocky person, his own face ought to cover even more of the picture.
I never got the opportunity to have a real lift made like this.
OK, I found the advanced material settings where I can add more reflections.
V-Ray skills looking good…especially your grass
