I know that the three red lines on the luna waveform stand for some values, but I'm not sure how Blender interprets these lines. I assume the bottom red line is black and the top red line is white, so what is the line between those two stand for?
Hey ccash_flagg , can you share a screenshot? I'm only seeing one red line, which represents the "safe zone" of dark before it gets to pure black.
I'm using Blender 2.8, not sure where you are in 2.79 or 2.8 there, but here is my screenshot.
