菲涅耳着色器

Although the Fresnel shader can be used in any material channel (preferred is the Reflection channel), it does not affect the bump or displacement channels unless used as a secondary channel within Fusion or something similar.

尽管菲涅耳着色器可以用于任何材质通道(首选是反射通道) ，但它不会影响凹凸或位移通道，除非它被用作 Fusion 内的次要通道或类似的通道。

Note also the built-in physically correct 还要注意内置的物理正确性Fresnel 菲涅耳 in the Reflectance channel, which does not require the use of the Fresnel shader. 在反射通道，这不需要使用菲涅耳着色器

It’s hard to imagine not using a Fresnel shader when rendering glass. This shader can also make numerous types of materials look more realistic. Because the greater the angle at which you view a surface, the more reflective any surface becomes.

很难想象在渲染玻璃时不使用菲涅耳着色器。这种着色器也可以使许多类型的材质看起来更加真实。因为你看一个表面的角度越大，任何表面的反射率就越高。

Tip: 提示:
If 如果Refraction 折射 is set not equal to 设置为不等于1 in the Transparency channel, a Fresnel reflection will be calculated. This value can be set to 在透明通道中，计算菲涅耳反射。可以将此值设置为0.
