The next step is to add rectangular lights at the openings to supplement the sunlight system. It should be noted that this sunlighting system works only when using the Vray Physical Camera in the Camera settings, but I will go more in depth about this later. The exact location that the sun is placed in the scene doesn’t matter at all because, like in the real world, the sun shoot an infinite number of rays in a parallel direction to each other throughout the entire scene. This allows the user to have advanced control over the exact sun angle given a particular time of day and geographic location, or you can manually place the angle of the sun if specifics aren’t important. To do so, I use the sun tool that comes with Vray for Rhino. I then add an exterior light to simulate the sun coming in from each window. ![]() Once the lighting is set correctly, you will then have a realistic feeling for what the materials are doing and how they react to subtle changes. The reason to implement the lights before adding material is simple, with good lighting the materials will fall into their own. The next major step is to place lights in the scene. ![]()
