Sphere – the only specific thing here is the Radius and how it affects shadows.Next you can move into the options specific for each of the Lights discussed in this lecture.We can also control how lights interact with different components of a material i.e.Include/Exclude lists allow users to control which objects in the scene are affected.Talk about the Cast Shadows, Invisible and No decay options CG lights have the advantage of being able to do things which are impossible in the real world.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.

#CHAOS GROUP VRAY HOW TO#
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).Color, Temperature and Multiplier are the most direct settings to affect your render.Start with where the different V-Ray lights can be found and what possible light Types we have.Next you can move into CG lights and the settings they have, to reflect real world properties.You may add some examples of light sources used in photography i.e.Light color and temperature and how to create certain moods.Light size and its effect in creating shadows and highlights.The physical properties of light and how it behaves in nature i.e.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.
