DAZ PBR Skin to Substance Painter - looking for *precise* info

SnowSultan

I don't know how many times I've asked on here about getting similar results between Substance Painter and DAZ Studio, but I'm back again hoping a PA that has actually made a skin texture in Substance Painter might see this question.

Can someone explain what sort of shader setup needs to be made in Substance Painter to even come close to replicating the DAZ PBR skin shader for Genesis 8.1 and 9? The DAZ PBR uses odd spec/glossy maps that give bad results in Painter (either gives oily-like specularity or none at all), the AO map doesn't even seem necessary, and as always, SSS settings and Translucency maps in Studio seem to make no sense in any other program (still have no idea why grayscale maps aren't used).  I have tried various shaders and added all kinds of different channels, and nothing has worked. I also know that DAZ textures are naturally designed to look their best in DAZ Studio, but with so many textures being created using Substance Painter, I don't know why it isn't easier to connect them back to where they came from and get even remotely useable results.

Thanks in advance for any advice.
