# V-Ray Light

This lesson gives a basic sample lesson plan for introducing the V-Ray L= ight in its Sphere, Plane/Disc and Mesh modes. =20 =20

### Lecture

• Since this is the introductory lesson in V-Ray lights you may first spe= nd some time to review how light works in real life and how it=E2=80=99s us= ed as an artistic expression. You may spend some time on
• The physical properties of light and how it behaves in nature i.e. inte= nsity 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. sof= t 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 possi= ble light Types we have
• Color, Temperature and Multiplier are the most direct settings to affec= t 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 r= eal world light sources)
• Talking about shadows as a creative expression it=E2=80=99s important t= o note that in V-Ray the softness of shadow depends on the size of the ligh= t
• CG lights have the advantage of being able to do things which are impos= sible in the real world. Talk about the Cast Shadows, Invisible and No deca= y 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 disc= ussed in this lecture. Sphere, Plane/Disc and Mesh
• Sphere =E2=80=93 the only specific thing here is the Radius and how it = affects shadows
• Talking about Disk and Plane the important settings are
• Double Sided =E2=80=93 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 parame= ter
• Mesh light is useful to create light sources with complex shapes

### Demonstration

• In this cycle, you are going to demonstrate the different modes and set= tings of the V-Ray Light. Use the provided handouts and scenes as a guideli= ne or create your own exercises
• The scene Vase (Est).max is the same scene used in the demonstrations b= ut it has shaders applied.

### Activity

In this cycle, you are going to let your students experiment with the pr= ovided scenes. You may want to give them the provided handouts to use as a = guideline.
