With Bump or Displacement the sub settings are just as important. The settings of -0.010 and 0.010 are VERY low, I suggest you read the DS3 PDF manual, it gives a very good explanation and those still apply in DS4.5.
That was it, thanks! adjusting the Negative Bump and Positive Bump sliders did the trick. (sliders “Minimum” and “Maximum” or “Negative” and “Positive” in DS3 manual depending on whether you’re looking at the picture or text).
I didn’t even see them, in fact. I normally pose in DAZ Studio and render in Bryce, I’m going to use that as my excuse.
