![]() There are various ways to connect the mib_amb_occlusion node to the desired object.ġ. The ambient occlusion node can be found in the Hypershade under Create > MentalRay Textures > mib_amb_occlusion. Introductionįirst off the ambient occlussion node is a mental ray node so, so u would require the mayatomr plugin to be enabled. The mib_amb_occlusion node come with a variety of attributes to customize the final rendered AO image. It is moderately low on render time, and has significant advantages in the final look of an image. So what basically this shader does is try to re-create the effect of ambient occlussion. The soft appearance achieved by ambient occlusion alone is similar to the way an object appears on an overcast day. As a result, points surrounded by a large amount of geometry are rendered dark, where as points with little geometry on the visible hemisphere appear light. Rays which reach the background or “sky” increase the brightness of the surface, whereas a ray which hits any other object contributes no illumination. Ambient occlusion is most often calculated by casting rays in every direction from the surface. Occlusion is a fast and simple method to simulate the effects of global illumination.
