Occlusione Ambientale

The Ambient Occlusion shader computes how much the hemisphere above the shading point is occluded. This can be used for procedural texturing, for example to add weathering effects to corners only.

For Cycles, this is an expensive shader and can slow down render significantly. If render time is a concern, using Pointiness from the Geometry node or baking Ambient Occlusion will result in faster renders.

Nota

Cycles Only The Ambient Occlusion node will not produce a valid result on objects that are either a Caustic caster or Caustic receiver while the scene contains a active Caustic caster, Caustic receiver, and Shadow Caustic Light.

Ingressi

Colore

Tint for AO output color.

Distance

Distance up to which other objects are considered to occlude the shading point.

Normale

Normal used for ambient occlusion; if nothing is connected the default shading normal is used.

Proprietà

Samples

Number of samples to use for ray-traced ambient occlusion sampling. Keep as low as possible for optimal performance.

Inside

Detect convex rather than concave shapes, by computing occlusion inside mesh.

Only Local Cycles Only

Only detect occlusion from the object itself, and not others.

Uscite

Colore

Ambient occlusion with color tint.

AO

Ambient occlusion factor without color tint.

Esempio

White AO shader.
