UTCI Heatmap Issues

Hi,

I’m having issues with results from a UTCI study. The heatmap has an irregular pixellated look (please see attached). Can someone shed light on what the issue was and how I can resolve it?

Attached also are the gh and rhino files.

Thank you,

That’s the result of Radiance stochastically generating rays for the shortwave solar analysis. If you improve the input Radiance parameters using the annual option of the HB Radiance Parameters component, you can get it to go away or at least be much less.

Or you can just be happy with an error that probably less than 1C since improving the Radiance parameters can make the calculation a lot longer.
