This DVD covers a general introduction to the principles of Global Illumination, which are essential to the understanding of this specialized form of lighting. While the series primarily uses V-Ray as the render engine in a 3ds Max environment, those using other GI renderers will also benefit from the conceptual techniques described. From the general concepts of reflected specular and diffuse light, to sky lights and image based lighting with HDRIs, Christopher shows how to light scenes using real world lighting in a fully reflective environment. He also demonstrates how to tackle the issues of animation by finding the most optimal way to bake lighting for exterior sets. This series is geared toward the CG artist that already has an intermediate understanding of direct lighting and is making the transition to GI lighting. ...
