I did some test on Filter Sharpness parameter in the vrayhdri loader and here the results.
I used elliptical filtering algorithm and vray default render setting (using vray 3.50.04)
test has been done with 8 different filter sharpness size : 0.01, 0.1, 1.0, 4.0, 16.0, 64.0, 256.0, 512.0

as expected 512 has a broken result.

you can download all the result images file from here (RGB and sample rate are included in a ZIP file)

Interesting results. But where exactly can I find the sharpness parameter? Do you mean Blur value?

no, it is accessible from the script and not represented in UI at the moment.

I see. But the value seems somewhat inverted. The smallest value of 0,01 hast the biggest amount of blur.
