How irradiance mapping works

Irradiance mapping is probably the most widely used of V-Ray's primary bounce GI engines, simply because it is effective, flexible, and at the base level, pretty easy to use. In this video, we just want to run over for you the basics of how a irradiance mapping works, because, well, understanding the basic principles of the technology can go a long way towards helping us make good production choices when it comes to our irradiance mapping parameters. Now, if we just pull up our Render Settings window, go to the main toolbar, use the icon to pull out for ourselves, inside of the Indirect Illumination tab, you can see we have Irradiance map set as the Primary bounce engine.

So let's just come and look at some of its controls. A couple of things we need to note right from the start are, firstly that irradiance mapping is a view-dependent GI technique. This means that the global illumination solution is calculated only from the rendering camera's point of view. If we move the ca...
