Since the IES file fully defines the light distribution from the source, the Beam Angle option is removed. Selecting a light fixture’s photometric definition via the manufacturer’s provided IES file is the best way to get the most realistic results. This will have an impact on the way light falls on adjacent surfaces, such as walls. Notice the representative cone size changes when the Beam Angle is adjusted. Once placed, and when selected, we can adjust the Luminous Intensity and Beam Angle… another option is to assign a photometric IES file to get a more accurate product-based light distribution these files are provided by the light fixture manufacturers. Notice, the light source cone follows the cursor during placement. Two additional points are selected to aim the light source. Simply click the Spot tool, and then start by clicking in the center of the light fixture. In this example, a Spot object is placed relative to the modeled lighting fixtures in the ceiling. From here, you can place new objects and edit the previously placed ones. To place a light source from within SketchUp, select Extensions -> Enscape -> Enscape Objects, or click the same command on the Enscape toolbar, as shown in the image below. It is easy to see the added effect of the additional light sources. The first image above jumps ahead and shows the results of adding lighting sources in the SketchUp image, they are defined by the orange-colored cones. Take a minute to notice the various light fixtures and materials employed. This is a private residence sample project developed by the Enscape team. The next image simply shows the exhibit model in the native SketchUp application. In this post, I will focus on the light sources. So, to enable us to put lights in SketchUp, the Enscape team created a tool to add special objects which are recognized in Enscape light sources, sound sources and Linked Models (i.e. Unlike Revit, SketchUp does not have a way to facilitate light sources.
