SSS-type material for RS3D V4.5 SP1

Load as a project, untick replace.
Slap the material on an object, use the post image and render setting.
Options:

Surface Color
 Std. surface color

Surface Transparency
 Surface Filter transparency, defines the volume's color.
 
Volume Sampling
 Std. Volume sampling, set to a higher value if you need accurate shadows inside the volume.
 
Volume Thickness
 The higher the value, the faster the material absorbs light.
 
RayCount:
 More rays->less grain
 
Volume illumination Disabled
 Unticking this lets you define volume illumination with the curve based on dotproduct(volume : ray, light : ray)
 In other words, giving the curve a high value around -1 illuminates the volume strongly when backlit.
 
Tips
 -For reflection visibility, change surface finishing->if(recursion) to a higher value (default 1.01)
  and add traced ray : illumination += (traced ray : SSS_ish_Diffuse) to your reflective material's secondary ray
  
 -You can bundle the shader's output with GI to save in post fx render times (one blur instead of two):
  change the raytracer-object's output to 'diffuse'. You'll need to boost the volume color a bit though, as it is
  now multiplied with surface color
  
 -_Don't_ use this on an object that has transparency>0...
 
New in this here finest of the fine release: A new, shiny sample project.
