Using this paper: http://graphics.pixar.com/library/ApproxBSSRDF/paper.pdf This model gives less blurry results than the Cubic and Gaussian we had implemented: - Cubic: https://developer.blender.org/F279670 - Burley: https://developer.blender.org/F279671 The model is called "Christensen-Burley" in the interface, which actually should be read as "Physically based" or "Realistic".
