How to have detailed illuminance map by Radiance (in OpenStudio)

I have watched Radiance Integration video of Rob which was so useful. I would like to know why the graphic of my illuminance map is different than Rob. The plot of Rob (image A) has small pixels and detailed map as a result

image A image description

but for me (image B) pixels are larger.

Would you please let me know how can I have illuminance map like Rob?

(My system: windows 10, core i7 -4700HQ CPU) (Openstudio: version 1.11)

Rob's map is using linear interpolation. It is NOT more detailed. The smoothing function only makes it LOOK nicer, but it does not add detail to the simulation.

You mean like this? Here is an illuminance map that looks like me:

Sorry. In all seriousness, the illuminance map density in that example is no greater than yours, the colors are just being interpolated across the points with a smoothing function. If you look at the peak in the image, you can see the red color sort-of bleeding across the edges of four patches -- an artifact of the interpolation that exposes the true point spacing (and thus the patch size).

As to how to interpolate the colors in Results Viewer, this is a good question. The last version of that app I have does not seem to have that ability anymore, and Results Viewer does not ship with OpenStudio at all, as of v2.2.0. You can install previous versions of Results Viewer by following Jason's answer to this question. There are a couple of other threads here on UH that speak to other data visualization options as well.
