In this segment, we’ll focus mainly on creating and instancing window and ceiling V-Ray lights. The first step is to create V-Ray window lights and instance V-Ray ceiling lights. The next light we’re going to create are the window lights. While the light is still selected, hold down the shift key and move the lights created. Instead of instancing it, we’re going to copy this light as it will have a different functionality. Let’s rename it as ‘_Windows.’ While the light is still selected, open the modify panel. Because this light will be emulating the diffused emit light in shadows coming through the windows, we’ll change its color to bluish. Next, we’re going to move and [indiscernible] the light outside the window to angle this arrow towards interior space. Enable the angle snap toggle button and change the rotation time to local, so you rotate in a correct angle. Let’s move the light so it’s centered around the window seen in the camera. We can also change it’s length and width to fit the window dimensions. Let’s move the light until it becomes visible in the camera view, and place it outside the window glass. To move location in a particular direction, we can also change the move tog to local. This adjusts and move the lights farther. The following step is instance them along the windows using some of the techniques covered earlier. Lights with the same functionality should always be instance. The more instance lights, the faster the renders will be. Let’s restrict selection to lights only to prevent lighting any other types of objects in the scene. Enable the geometry hide by category option. This will make it easier to navigate in the scene. Next, hold down the control key and select all the window lights. Change the move type from local to view, as it will be easier to move multiple objects at once. To copy the selected lights, hold down the shift key and move them. Choose the instance object and OK, and check the geometry hide by category options, and move the new lights to the other side of the building where the other glass windows are. Rotate them locally so the arrows are pointing towards the space inside. Adjust the lights so they sit outside the windows accordingly. Copy instance another window light. The following step is to start copy instancing all the ceiling lights using some of the techniques covered earlier. Place every single light to align with the self-illuminating light objects in the ceiling. Let’s do another test render to check the recent changes. Let’s check the before and after adding the new lights. The next step is to add a dome light in the scene. This will help emulate a diffused lighting and shadows for objects outside the windows. The segment is now concluded. The window and ceiling lights are key to emulate natural and artificial lights.
