The new EZSkin V3.4 is here:
https://kdrive.digital-paradize.com/app/share/116364/c9c3812b-e75f-42c0-842f-ca98da3a412c

The new plugin, based on PrincipledBSDF is here:

Some words of explanation: most settings are based on my humble experience. For example, in the common settings below:

- Bump's distance and strength are the one that works for my Vic4's. I have often seem them interchanged in many Blender examples

- in the same bloc, SSS anisotropy and Anisotropic are new params for the PBSDF node, and I like those as is, not sure it's correct

- the new EZSkin saves the path you have set: click OK in this dialog and exit EZSkin => definitely saved

- the nipples part have their own setting, so that one can set a different roughness (not sure that they are as glossy as normal skin), same for the face and the lips

-all the parameters lie in that huge dialog box, other settings (from the other buttons on the main dialog box) are ignored

- to active the blush: replace "face" by "face_blush" and "skin" "skin blush" here:

Remember that each section can be displayed independently using the top selector.

One last word with Poser 13: even though EZSkin works well in both the Pose Room and the Material Room, avoid its use in the Material Room. Quite often Poser truly HATES when a Python script modifies the organization of the nodes. Changing values aren't a problem but adding/removing nodes is often a no-go and ends up in an instant crash, especially when the currently selected material is updated by the script.

Once again: it's actually to be used with bump maps (or the generated pores, the code being the one in use by EZSkin since long ago). A version that can handle Normal map is on the way.

I remain opened to any suggestion (defaults values, other internal settings to offer as input of the compounds, etc.

HI everybody, especially the EZSkin users... 
In April, 2023, Ghostship created a thread dedicated to human skin, based on Cycles SSS: here.

For my needs, I have written an EZSkin plugin that is using more or less what were shared in the said thread, I mean: using the famous PrincipledBSDF node.
Actually, it handles all parts for Vic4's and Sasha's, even though the skin parts may be used for all other characters I think. Furthermore, blush can be added (face and ears), and even an hypno effect if you have the corresponding iris bitmap  (here, it comes from RebelMomy's Holly)

The material for the teeth is based on what Ghostship showed us.
If you're interested, I'd be happy to share. You will just need an update for EZSkin, of course compatible with the existing plugins.
Typical result:

I've put compound nodes everywhere, as I do love simple material setups with just the right parameters visible.
Note that actually it relies on Bump maps, but I have some characters that have none, but rather a normal map, and I'm going to prepare a version for those.

 Wooow 

Oopsies, thank you Richard

On Mac, there's an awesome program, full of functionalities to clean & optimise, but it isn't free, although not expensive CleanMyMac.

And no, I haven't anything to do with them: they don't need me 

Mouse left click, don't release, press the space bar, move your mouse. Works on Win & Mac. I think that's pretty much like Ph0t0sh0p and almost like Gimp.

Thank you Phil, I have updated the mirror on my site to your latest version of EZSkin also. :)

@Y-Phil

Thanks so much for the script updates. :)

If anyone has dowloaded the EZSkin 3.2ter, replace it with this one:
https://kdrive.digital-paradize.com/app/share/116364/fc59fb81-fa2c-4211-b8e1-5b2cbbcda55e

It's labeled "EZSkin3.3" as I don't know what comes after 3.2ter... 
The correction avoids the material shader to be unnecessarily cluttered with orphan nodes

Hello

Here: https://kdrive.digital-paradize.com/app/share/116364/91424416-1763-4bdf-bf2f-e0e7ec589478
You will be able to download EZSkin3.2ter, an update of EZSkin3.2bis. still for Poser 12+
The difference: it restores the file names, example with the famous suntan file name on my PC:

When

When trying to use Snow machine 3 with all materials selected I get the above Error. 

Any thoughts?

Even an empty material, based on PoserSurface, works.

Hi

"I no longer can make changes in the Pose Room" <-- that's a bit weird, I mean: if you can't see the Pose room, it may indicate a problem with the interface.
You can restore the original interface from the preferences

Then, once you have repositioned everything, use this:

Each dot represent a saved interface organization, it's a by room tool.

The general preferences respond to Ctrl-K under Windows. They are under the Edit menu:

Here you are: a Python 3.7 version of the snow machine. Its version is V3.0.0, and the name of the script differs from the original, to avoid any problem.
The Firefly part remains the same, the script has been adapted to the new environment, plus a few details, For example, it remains floating above Poser.
The advanced tab has one new parameter: the scale for the displacement node

You may download the Python file here:

I am of course opened to any suggestion to enhance it, as it relies on my mid-level knowledge of Poser's materials 
This year, the snow has a weird look, lol...
