Join Ryan Kittleson for an in-depth discussion in this video Adding ambient occlusion to the shaders, part of Digital Creature Creation in ZBrush, Photoshop, and Maya.
Ambient Occlusion or AO for short is a lighting trick that simulates the…appearance of shadows inside of crevices and between objects.…It's based on the idea that light doesn't reach inside places like that, as…easily as it does the surfaces that are out in the open.…It's a nice way to increase the detail and sense of realism in your renders.…So Ambient Occlusion doesn't literally exist in the real world, but it's…going to simulate effects, like this dark shadow here, where the belly is…very close to the ground.…
To start with, let's do a render so we can compare the before and after.…We've got our Perspective View here, and let's just click Render, let's Save…that image, and close the Render View.…Now, let's go to the hyper shade and pick the material that's applied to the ground.…In its Attribute Editor, we want to add a node to the Weight Channel.…So let's go over here, I want to shrink this down so we can see this better;…in the Weight Channel, we're just going to click on this checker box right here.…
