I have a character with some strange textures, and I don't know how to use them. For example for face i have these files:


Now, I need a node map, so I can put everything in it's right place, but I have no idea about what I need to do, because I'm too new to Blender and Material Nodes.
I want to use all of these files to create a realistic human skin material.

  • $\begingroup$ @JachymMichal Oops!, of course you can. I was imagining setting radii by hand? I'll get to it as soon as I can. In the mean time, Axel can pick up your adjustment. So you reckon that red map is RGB SS radii, not RGB SS color? It seems odd to have SS color the same as surface color? $\endgroup$

  • $\begingroup$ @RobinBetts Yes, it's seems odd at first. But that's just how SSS is implemented in Principled BSDF. The Subsurface slider actually multiplies the radius and also mixes Base and Subsurface colors. Other engines (V-Ray, Renderman, Arnold) have these as two separate sliders. $\endgroup$ Commented May 22, 2020 at 13:34

  • $\begingroup$ <tears of joy> Robin Betts just learned something new from me :).</joy> I just realized Mental Ray was discontinued long before I even started with 3D, you're like a wise elder around here :). $\endgroup$ Commented May 22, 2020 at 14:10

Here's a shot at what your tree might look like, as corrected by @Jachym.

enter image description here

  • Introduce the branches one at a time,starting with Diffuse color on its own.
  • Unlike the illustration, forget the AO branch to begin with. Plug the Diffuse map straight into the Base Color.
  • Then check the Normal. If you want to get a better view, you can temporarily unplug the Diffuse map to see the effect on a white object.
  • When that's OK, plug the Diffuse back in, and go for the Shininess.
  • Now go for the Subsurface Scattering. Split the Diffuse, and plug it into Subsurface Color too.
  • Plug the 'M' map into the Subsurface Radius.
  • Depending on the size of your model, adjust the 'Subsurface' slider down. (I would recommend scaling the model in Edit mode, to life-size, in whatever units your scene is in.) Plugged in as shown, the RGB values in the red 'M' map represent the distances R,G and B are allowed to scatter through the object, in Blender Units, before attenuating to 0. Those distances are then multiplied by the value in the 'Subsurface' slider.

This is hard to check without the file.. but I hope it heads in the right direction.

  • If you really need the AO, (the lighting shouldn't really need faking..), use an RGB Mix node set to 'Multiply' or 'Overlay' to mix it with the Diffuse map on the way into the Base Color.

There's every chance @Jachym will have to correct me again :)

  • $\begingroup$ i tried but couldn't get my desire result. i uploaded an file so you can see it better. link is up in my question. Thanks by the way. ;) $\endgroup$

    $\begingroup$ @JachymMichal I judged it by backlighting the hand.. it's actually too much, IMO.. If the fingernails stopped it, that would help. $\endgroup$

    $\begingroup$ I also noticed Random Walk sss method works great here (especially for the thin nails), and isn't much slower :). $\endgroup$ Commented May 23, 2020 at 16:31

    $\begingroup$ @RobinBetts Of course i did , 2 times i did XD , but guess what , I DID IT NOW !!!! little change in your nodes + my details made it Perfect ! not as much as emily but very acceptable. THANKS BIG MAN !!!!! Now i have lotta new question in my new posts. u gotta answer them all. ur cool. $\endgroup$
