Ambient occlusion in Alias

00:04

I have a model here that already has some basic shader assignment.

00:10

The first thing I'd like to do is create some more contrast by adding

00:14

ambient occlusion shadows to add more definition to the shapes.

00:19

I'll open the Ambient Occlusion Compute dialogue, and I

00:22

want the Object Scope to be All.

00:26

The other default settings are generally quite good for a first pass.

00:32

When you hit Go, you're automatically put into an Orientation Mode.

00:37

And here you can see there are some surfaces facing the wrong direction.

00:43

We'd like all the surfaces that are pointing towards you or facing outward

00:47

to be white.

00:49

By left clicking or left box-selecting

00:52

you can change the orientation of these surfaces.

00:57

Inspect your model and determine whether or

00:59

not everything is pointing the right direction.

01:01

Clicking the left mouse button or clicking the right

01:04

mouse button to flip it the opposite direction.

01:13

Next,

01:14

hit the Compute Occlusion button, and it'll take several minutes

01:18

to calculate and bake the shadows onto the model.

01:22

After the calculation is complete,

01:24

you can see we now have baked shadows that add more contrast in these hidden areas.

01:30

Select Pick Object to exit the Orientation Mode.

01:34

And you can see in Hardware Shade, these shadows are now applied with the shading.
