The goal was that the preview images should have more or less the same brightness. We then calculated this scene automatically for each IES file using python. After this process, there was "only" 160'000 data left.Īfter that we created a scene in Blender, where a light source hangs 5cm in front of a wall and 1m above the floor. Using python we read the data, hashed the content as MD5 and assigned the data to the individual manufacturers. We have enriched existing IES collections with manufacturer data and have reached almost 200'000 data in the end. However, it is cumbersome to find the correct file using try and error, as the manufacturer does not necessarily include a visual example.įor this reason this page was created. This data is provided by many manufacturers so that lighting designers can realistically simulate how a project will look when a specific light source is used.ģD artists also use this data to calculate their images more realistically. A simple box with 3 pin lights as shown in the image below.IES files describe how light from a lamp is distributed in a room. Collection here at SketchUp Texture Blog.Another collection of IES files can be found in the links below: Included is a complete database of IES files for current GE products. Its a powerful lighting design aid for GE directional reflector lamps. More IES files here if those don’t work for your particular version of V-Ray.You can also download the GE Light*Beams 3.0 software at the bottom of this page. You can download IES files files of your own choice from here GE Lighting and more here IES Maps and a SketchUp light fitting here. In this simple tutorial we are going to set up three basic pin lights using imported IES files.
I have a new second tutorial, just published called Basic IES Light Tutorial using V-Ray for SketchUp. I use V-Ray release version 1.48.90 in it, which is a much better and stable release.
Lamp manufacturers create these files for accurately simulating their lights and now we have the ability to add IES profiles (for light accuracy).
IES (Illumination Engineering Society) is a standard digital file in ASCII format, which measures the distribution of light, in other words the intensity of the light and its shape. V-Ray works within the SketchUp environment allowing users to be able to efficiently incorporate the task of rendering within their current workflow.
1.48.66) has the new added feature of IES Lights and Spotlights. IES Light Tutorial using V-Ray for SketchUp
