倒角节点

仅限 Cycles

倒角 着色器节点可用于渲染圆角。与凹凸贴图类似，它只影响着色不修改几何体网格。边缘上轻微的圆角有助于实现真实世界中的镜面高光效果。

Note that this is a very expensive shader, and may slow down renders by 20% even if there is a lot of other complexity in the scene. For that reason, we suggest to mainly use this for baking or still frame renders where render time is not as much of an issue. The Bevel modifier is a faster option when it works, but sometimes fails on complex or messy geometry.

Note

The Bevel node will not produce a valid result when:

• The object is either a Caustic caster or Caustic receiver while the scene contains an active Caustic caster, Caustic receiver, and Shadow Caustic Light.

• 当使用Optix渲染后端时激活了 开放着色语言。

输入

半径

边缘上倒角的宽度。

法向

Normal to apply bevel on top of, to be combined with a Bump node for example.

属性

采样

着色器的采样数。更大的采样数可以提供更准确的结果，但渲染速度也较慢。默认值为4，适用于大多数情况。通过使用更多AA样本来解决所有的噪点。

输出

法向

标准的法向输出。

示例
