3DS Max - Vray Frame Buffer - Real Zoom explained

In this tutorial, we will look at the difference between the regular zoom inside the Vray Frame Buffer, and the Real zoom. The benefit of using Real zoom is that it acts as if you're getting closer to the actual geometries in your scene and rendering them, also, in this mode you can check out other parts of your scene, not included in your actual rendering limits, without the need to mess up your camera location, or, if you're in a perspective viewport, messing up your viewpoint.
