Understanding ambient occlusion in mia_material
Ambient occlusion is a shading effect, that changes the colors of surfaces based upon distance. If two surfaces are close together, then ambient, or indirect illumination, can't reach into those cracks and crevices very easily. Aclusion means blocking and the aclusion therefore is the blocking of ambient light with a blocking of the indirect light. In this case that would mean blocking the final gathering. That's our indirect light source in this particular scene. We can add that by turning on some switches in mia material and the simplest and easiest way of adding the effect. However, as we will see in the next movie, I want to extend that technique a bit because I want to block not just the indirect illumination, but also the direct illumination and reflections. But first let's take a look at miah material and what options we have there. Let's go to the hyper shape, window, rendering editors, hypershape. Select the chromie material and go the attribute editor control A. And scroll…
