Ok, we're used to say in  French that a picture is worth 1000 words, so here's why the EZCycle plugin will not work at 100% with EZSkin3.1 and Poser13 actually: the SubsurfaceScattering node used has quite changed:

EZCycles tries to connect the output of a REdFIlter node to the Texture Blur.

I'm not sure what the effect is, but I managed to create an update to EZSkin3.1: now EZSkin3.2, it simply avoid any error if a connection can't be made.
You may download it from here: https://kdrive.digital-paradize.com/app/share/116364/5eb72f71-c932-456e-ae47-a8109857068c

It's only the Python script, just overwrite the actual 3.1.

I have tried an example with Sabby's Amber skin and two parameters changed. When EZSkin is loaded, clic on CFG after having selected the right Shader Engine:

Then, increase HighGloss and LowGloss values, this will increase the Rougness accordingly, thus you'll decrease the oily effect with Poser13's CycleX implementation.

I'm decided to write a new plugin, something like "Ghostship's Cycles", to add the this list:

I don't know when it'll be ready but that's decided
