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

 

 

Lecture


  • Since this is the first lecture on the topic of shading it is good to begin by discussing some common terms like
    • The difference between a shader and a material
    • The main components of a CG material – Diffuse, Reflection and Refraction
    • Fresnel reflections and Index of Refraction
    • The difference between highlights and reflections
    • Self-illumination
    • Translucency
  • You may want to spend time discussing how light is reflected/refracted by different materials in the real world to create different looks
  • Using photos of real world materials may be useful to better explain the concepts
  • Next you can move on to explain the main components of the V-Ray Material
    • It is a layered material and layers are blended so that the Energy Preservation Law is not broken – i.e. a material cannot reflect or refract more light than it is receiving
    • Main layers – Diffuse, Reflections, Refractions
    • Secondary layers
      • Self-illumination
      • Translucency – builds on top of the Refractive layer
  • You may discuss the usage of texture to control certain parameters and the importance of proper UV maps
  • Bump and Normal mapping are also shading effects that can be discussed during the lecture. It is important to point out that the actual geometry is not affected here.
  • We have provided you with a lecture that covers all the important settings of the material that need to be explained
  • Since the topic is You may want to point out that things will become much more clear during the Demonstration and Activity cycles

 

Demonstration


  • In this cycle, you can use the provided scenes and handouts to demonstrate the different components of the V-Ray Material. It is up to you to decide which ones to use, additionally you may prepare your own materials if there are specific examples you’d like to show

Activity


  • 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
