This lesson gives a sample lesson plan for involving the Random Color Techniques module into a lecture.
- Discuss cases where you may need to create multiple shaders that are almost the same except for one or two parameters.
- Fruits in a bowl can have tiny variations in the color
- Tiles on a wall have the same type of Fresnel reflections but different diffuse colors
- Glass jars can have the same material with different reflection colors
- You may want to find and show some images that demonstrate the above examples
- Discuss how we can use the V-Ray Multi-Sub Texture to feed different colors or textures to a parameter of a material.
- Discuss the subject of Object IDs and Material IDs and how to assign them
- Discuss the subject of custom object attributes and how to assign them
- Discuss how to use the V-Ray User Color utility map
- Note that the subject will get much more clear during the demonstration cycle
- In this cycle, you can use the provided scene and handout to demonstrate how to use the V-Multi-Sub Texture map and the V-Ray User Color utility map to create color variations in a shader
- In this cycle, you are going to let your students experiment with the provided scene. You may want to give them the provided handouts to use as a guideline
