Re: light bug. I cannot reproduce this, Is this Firefly or Superfly? What sort of lights? My lights work fine and shadows are cast properly after reloading a scene or changing lights.

To which I reply:

I use Superfly exclusively these days.  Check the properties tab for lights.  I find that when I load scenes I created in Poser 13.3.895 into 13.3.1009 the check box for shadows is not checked.  No problem to go through and check it on all lights and things render fine.  I'm uncertain at this point about reloading scenes in 13.3.1009.  It's not a big deal but it's a nudge.  If my two computers are the only ones in the world where this happens, I can live with it. =)

For what it's worth, both my machines run Windows 10 and have Nvidia graphics cards.  The older box has an AMD CPU and the newer one has an Intel CPU.  I'm not an expert on hardware but I'm thinking all the talk about Macs doesn't apply to me. ;-)
