In NSC Shaded Model I want to colour pixels by last analysis. I have a simple model with a couple of detectors; they both display the correct profile in the detector viewer but in NSC Shaded Model only one detector shows the plot. As per below - one detector shows fine ( the source array ) but then the other one ( the big black square ) doesn’t show the irradiance in the NSC Model but its fine in the detector viewer.

As far as I can see the settings for both detectors are the same ( acceptance angle etc ).  I’ve seen this before and obviously missing something but what . . .

The big black square should show this . . . ( which is displaying fine in detector viewer )
