How can I view or generate Radiance Illuminance Map and Radiance scene rendering using Radiance Daylighting Measure in OpenStudio.

I tried using DView, but it does not generate the illuminance map. I don't know if there is another way to try to generate this map and scene rendering.

Unfortunately, DView does not read illuminance map data. The Radiance measure produced by the OpenStudio dev team at NREL was designed to work with the (deprecated) ResultsViewer application, and there has been zero support for it since about 2016. If you wish to view/plot the spatiotemporal illuminance map data generated by the OpenStudio Radiance Daylighting Measure, you'll need to roll your own solution.

Your follow-up notes correctly point out that the SketchUp plugin, which contains tools to place the lighting analysis objects needed for the Radiance measure to work, is not supported in the latest version(s) of SketchUp. If you sense a catch-22 situation, you would be correct...

This tutorial shows how to use the Sketchup Plugin to view daylighting. There is also this helpful video that explains how you can view output results in the sketchup plugin

You should also check out the "View data" measure directly in OpenStudio - it allows you to view any output variable. I would assume that could be used for daylighting but I've never used it for this purpose before. You can follow this tutorial on how to add and use the view data measure:

Hope this helps.

The question is specific to visualizing illuminance map data, which is not supported at all by the current version of OpenStudio or its tools.

My mistake. I don't use that feature much but remembered I saw it existed so thought I should share. Thanks for pointing that out

Thanks for the replies. I already watched these NREL videos and the current version of OpenStudio no longer has these options used in the videos. Do you know if there is another application that can read the radiance generated sql file? I don't understand much about programming.
