环境光遮蔽

Ambient Occlusion node.

环境光遮蔽 节点计算被遮蔽点上方的半球形空间的遮挡量。该节点可用于程序贴图纹理,例如,仅向拐角处添加风化效果。

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.

Note

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.

输入

颜色

用于AO色彩输出的颜色。

距离

遮蔽点可以被其它物体遮蔽的最远距离。

法向

如果不与其它节点连接,则使用默认遮蔽法向。

属性

采样

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

向内

通过计算内部网格的遮蔽来检测凸面,而不检测凹面。

仅局部 仅适用于Cycles引擎

仅检测对象本身的遮蔽,而不检测其他的遮蔽。

输出

颜色

含有色彩的环境光遮蔽。

AO

不含有色彩的环境光遮蔽。
