This lesson gives a basic sample lesson plan for a lecture on using V-Ray RT.




  • You can start with discussing the main idea of V-Ray RT
    • It’s a progressive rendering engine that can be used in ActiveShade mode
    • The rendering appears inside the V-Ray Frame Buffer and thus can use the Render Region and Track mouse while rendering
  • You can explore some of the benefits of using V-Ray RT
    • Speeds up the shading and lighting process
    • Makes it easier to work with clients or visual directors
  • Some important options that should be discussed include:
    • Trace depth and GI depth – both will affect the render times as well as the “physical accuracy” of the rendered output
    • Override mtl – this option is extremely useful when setting up the illumination of the scene
  • When you talk about performance it’s important to point out that improvements in performance comes from the size of the chunks of data that are sent for calculation at each pass. This means that faster rendering means lower interactivity and vice-versa.
  • Another important point is the pros and cons of running V-Ray RT on CPUs and GPUs. The main disadvantage of GPUs is that they are limited in terms of memory
  • You can point out that V-Ray RT can render directly in the viewport as an Extended Viewport
  • Finally, you can point out that V-Ray RT can be used as a production renderer by setting up a specific render limit


  • In this cycle, you are going to demonstrate the main functions of V-Ray RT in the scene we provided or in one of your own scenes
  • You can use the provided handout as a guideline or perform your own demonstration.


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