This lesson gives a sample lesson plan for involving the Volumetrics module into a lecture.




  • Start with discussing and showing some pictures of real world cases of exterior scenes with fog or smoke
  • Talk about how the atmosphere affects the way exterior photos look, especially in the case of large scale photos of a city or a mountain range
  • Discuss the V-Ray Environment Fog
    • Physically accurate way of calculating how light behaves in a medium composed of millions of tiny particles
    • Can be used to create effects like fog, smoke or clouds
    • Can be used along with 3d textures to create complex effects
    • A self-illumination component allows us to fake GI to reduce render times
    • The effect can be confided within the volume of a gizmo or any geometry
    • The user can control which lights affect the fog
  • Discuss the V-Ray Aerial Perspective
    • Not entirely physically accurate but fast
    • Good for simulating thin mist
    • Volumetric shadows are not calculated
    • Mist can be tinted
  • V-Ray Aerial Perspective and V-Ray Environment Fog can be used together to produce more complex effects


  • In this cycle, you can use the provided scenes and handouts to demonstrate how to set up the V-Ray Environment Fog and V-Ray Aerial Perspective


  • 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
