Remove background from psSAR surface viewer

[yiyang]

As shown in the figure, after I calculated the psSAR-10g of the human body model with psSAR Evaluator, even though I have masked out the background (with Mask Filter and checked "Crop Background" at psSAR Evaluator), I always get this kind of field distribution with background when I use Surface Viewer. Is there any way to remove this background?

When you used the Mask Filter, did you check the option 'Invalidate Masked Values'? This will set the Background to NaN, which should hide it. Otherwise, the Background value will be changed to a user-defined replacement value, which would still show up during visualization.
