I don't think so, because mine is Design version and it works. Maybe there's some glitches with Soulburn scripts installation? Does other scripts works as supposed?
Yes, they work or at least the ones I tried. I found really strange because I applied the script to a geometry I was working on. The geometry goes entirely white. So, I tested on a new cube and nothing happened. I never tried this script before at work, so I don't know if it worked from the beginning. This script is the only option I have to create a quick dirt around the corners.
UPDATE:
The script doesn't create any vertex maps if the geometry has some chamfered edges. Am I wrong?
