Added 2018-05-14 21:24:52 +0000 UTCLooks like ZBrush decided to put this horizontal line in the displacement map for Jo's arm. This was causing some nasty artifacts when she rendered. Glad I looked at it so quickly.
Had to install a paint program that can edit 16-bit images. Fortunately it's free. It's called Krita in case you want to take a look. I should have this cleaned up and rendering restarted momentarily.
