This lesson gives a sample lesson plan for involving the V-Ray Sub Surface Materials module into a lecture.




  • Start with discussing the sub surface scattering effect and give some real-world examples
    • Inorganic materials like wax, plastic, marble etc.
    • Organic materials like fruits, milk, skin etc.
  • In V-Ray we can create SSS effects using one of two materials – V-Ray Fast SSS2 and V-Ray Skin
  • V-Ray Fast SSS 2
    • Presets – the presets can be used directly and are very useful as a starting point to build custom shaders
    • Scale – the scale of the geometry is important for the way the material looks. This parameter allows the user to control the strength of the SSS effect
    • Diffuse and SSS layer holds the settings for setting up sub-surface scattering
    • Specular layer allows us to add reflection on top of the SSS
  • V-Ray Skin
    • Mainly used to simulate skin, this material can be set-up to create all kinds of SSS materials like plastic, wax etc. Because it has multiple layers some very complex and convincing effects can be created
    • Three SSS layers that can have a different depth of effect and an amount parameter to control how strong the contribution of each layer is
    • Two specular layers allow the user to have two different reflective coats, each can have a separate color and glossiness and the Amount parameters control how strong the contribution of each layer is


  • In this cycle, you can use the provided scenes and handouts to demonstrate how to set up each of the two materials in order to create a translucent plastic material


  • In this cycle, you are going to let your students experiment with the provided scenes. You may want to give them the provided handouts to use as a guideline
