I believe the reason it was D|S specific was because it had poses to apply the displacement maps only, which wasn't doable in Poser. That was until Cliff Bowman came up with a script which did that, and semidieu then did one too.

I used the maps at a low setting in this image, http://www.renderosity.com/mod/gallery/index.php?image_id=1903437

If you do use them in Poser and you use gamma correction, then as said above remember to set the custom gamma for them (easily done with the changeGamma script included in the scripts menu MaterialMods folder) to 1 as shown in DarkEdge's post above.

 

More recently there was more of a problem using them with sss but I'm pretty sure that was cleared up with SR3.
