Description Update

7 skin shaders:
  • SkinShader_1_Mul
  • SkinShader_1_Add
  • SkinShader_2_Mul
  • SkinShader_2_Add
  • ResinShader_Mul
  • ResinShader_Add
  • SkinNoSSSmap

  • 4 test shader:
  • TestSkinShader1
  • TestSkinShader2
  • TestResinShader
  • TestNoSSSmap




  • XPS map-driven SSS Fast Skin Shader - to emulate human skin - with the  benefits of using the Subsurface Scattering Effect for translucent materials such as skin, wax, resin, ceramics, porcelain ...

    I have improved my subsurface scattering (or SSS ) shader for XPS . You can download it in the upper right corner.

    The model, used in this preview, is Detroit: Become Human: Chloe Hostess  by   (DBH), ported to XPS by myself.
    The SSS maps are taken from this old  Detroit: Become Human - Chloe upload by

    Without SSS  sta.sh/0wykzzvcb8n
    With SSS       sta.sh/01yco3ancyvn

    How to use the XPS SSS shader?
    - Download the SSS shader, using the "Download" button on the upper / right of this derivation
    - Unpack it into the "XNALara_XPS\shaders" folder

    - Load your model in XPS
    - Assign the SSS map into the XPS "Material Editor" slot, labeled "specular map"
    - Save the model as an "New Generic File Format" (Modify->Save as NGFF)
    - Edit the material lib file (.mtl) with a text editor and seach the skin parts. (I have edit "Head", "Body", "Arms" and "Hair")
    - Add for this translucent materials the line "shader SSS;SkinShader" (without the quotes). 


    Result Example

    newmtl ModelChloe-Head_Material017
    Ks 0.1 0.1 0.1
    map_Kd Chloe_Face_Alb.png
    map_Kn Chloe_Face_Nrm.png
    map_Ks 38A0B_sss.jpg
    sc +X -Y +Z
    cm none
    opaque yes
    shader SSS;SkinShader_1_Mul


    Dont worry, the setting for "opaque" is yes; the shader makes that the light rays will penetrate the surface and be reflected by the values of the SSS map.

    The used DBH SSS map was: 38A0B sss
    Alternate, you can use this DBH map: Head Sss

    The SSS map contains 3 color layers (RGB: thickness, roughness, backlit)
    In XPS, with "Ctrl + J", the first slider control the thickness subdermal map, the 2nd slider the roughness layer and the 3rd slider control the backscatter effect.
    The fourth slider affects the entire subsurface scattering effect.

    The shader is very fast and works in realtime. The best result, you will get with a subtil BLOOM post process parameter (alos in real time).


    // SubSurface Scattering (SSS) Shader for XPS 11.8.8
    //
    // Epidermal color map in "diffuse map" slot (map_Kd)
    // SSS Subdermal map in "specular map" slot (map_Ks)
    // Red channel: thickness map (depth map); white is thin, black is depth subdermal skin
    // Green channel: roughness map; white is smooth, black is rough
    // Blue channel: backlite map; white is thin, black is opaque
    // RGB values can be adjusted with Ctrl+J ; 4th slider control all channels at once
    //

    No., the shader is for XPS.
    Yes, the model works on Blender.

    Every shader is just for one target system, and the model maps must match for this shader. If somebody, Claims "This is a universal skin shader for blender that works on DAZ, XPS, etc... ", like here ,  it's must be just a lie to make money by robbing naive people. There is no such thing as a "universal" shader!
