lol, it looks scary, but it's actually not some advanced technique, it's just the name of the button - "Gaussian blur." Before, there was only one slider that adjusted how much the texture would be blurred. Now there are four, but I still only use the first one.

by the way, I was a little mistaken, this Reaper is ID901, not ID900. ID900 is the new Necrolich for me.
I've re-uploaded the archive.
