What bump setting are you using? Poser uses very small bump settings. Like, under 1. Well under. Skin should be something like 0.01. I usually have it set to less than 0.1, even for fairly rough objects.

Reduce the JPEG compression?

Yeah, it looks like poor antialiasing due to low resolution or highly compressed bump map. Less compression and higher res would solve it most likely.

Tools :  3dsmax 2015, Daz Studio 4.6, PoserPro 2012, Blender v2.74

System: Pentium QuadCore i7, under Win 8, GeForce GTX 780 / 2GB GPU.

If you are using P5 or higher turn texture filtering on. Nerd3D

I highly recommend using PNGs for bump, displacement and transparency maps. You cannot get a true black or white with JPEG.

[slaps forehead] Can't believe that the 'no true black areas with jpeg compression' thing has never occured to me. DOOH!
