Backlight Shader

背光着色器

Backlight allows you to gather illumination (only from real light sources, i.e., no polygon lights, GI, etc.) from the back face of an object. This gives the ability to create translucency effects with backlighting, such as rice paper or a thin leaf lit from the opposite side complete with shadowing.

背光可以让你从物体的背面收集照明(只有真实的光源，即，没有多边形灯，GI 等)。这使得能够创建与背光半透明效果，如米纸或薄叶照明从对面完成阴影。

The most likely place to use Backlight is in the Luminance channel.

最有可能使用背光的地方是亮度通道。
