Ok.  Two more renders, this time using your indoor light set 2.  the first is without VSS, the second is with.  I lowered the Min Shading Rate to .25 and the hair is starting to look better.

I'm on a Mac and I am having a problem with the buttons.  I use File -> Run Python Script to run vssMainButtons.py and it runs fine and adds the buttons to the Python Menu.  However if I click on any of the three buttons, nothing happens.  The bottom Main Menu button works fine.  I can run macro1.py using File -> Run Python Script and it looks like it's working (I think I remember you saying that macro1 and wacro1 are the same - if not, I need to re-do all of these renders).

I added a print stqatement to vssMainButtons.py to show me vssFolder and it's getting the correct path (without using the hack), and I quickly got lost trying to figure out what was happening next.

If there is more I can do to help troubleshoot this, let me know.
