This lesson gives a basic sample lesson plan for introducing the V-Ray Light in its Sphere, Plane/Disc and Mesh modes.
- Since this is the introductory lesson in V-Ray lights you may first spend some time to review how light works in real life and how it’s used as an artistic expression. You may spend some time on
- The physical properties of light and how it behaves in nature i.e. intensity and decay
- Light size and its effect in creating shadows and highlights
- Light color and temperature and how to create certain moods
- You may add some examples of light sources used in photography i.e. soft box, spot light etc.
- Next you can move into CG lights and the settings they have, to reflect real world properties.
- Start with where the different V-Ray lights can be found and what possible light Types we have
- Color, Temperature and Multiplier are the most direct settings to affect your render
- It is important to talk about the Units parameter and how to use it to create physically accurate lights (if they want to match the intensity of real world light sources)
- Talking about shadows as a creative expression it’s important to note that in V-Ray the softness of shadow depends on the size of the light
- CG lights have the advantage of being able to do things which are impossible in the real world. Talk about the Cast Shadows, Invisible and No decay options
- Include/Exclude lists allow users to control which objects in the scene are affected
- We can also control how lights interact with different components of a material i.e. Diffuse, Reflection and Specular
- Next you can move into the options specific for each of the Lights discussed in this lecture. Sphere, Plane/Disc and Mesh
- Sphere – the only specific thing here is the Radius and how it affects shadows
- Talking about Disk and Plane the important settings are
- Double Sided – note the relationship with the Units parameter
- Both lights can be Targeted
- Both lights can use a texture for their color
- Both lights can be turned into spot lights using the Directional parameter
- Mesh light is useful to create light sources with complex shapes
- In this cycle, you are going to demonstrate the different modes and settings of the V-Ray Light. Use the provided handouts and scenes as a guideline or create your own exercises
- The scene Vase (Est).max is the same scene used in the demonstrations but it has shaders applied.
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.
