合并/分离着色器节点¶
所有这些节点基本上都是一样的：
分离：从复合颜色通道将图像拆分出来。
合并：将复合颜色通道的图像重新组合。
These nodes can be used to manipulate each color channel independently. Each type is differentiated in the applied Color Space.
In compositing and texture context each node supports the Alpha channel. In the texture context only RGB color space is available. In the shading context of Cycles combine and separate nodes are added for HSV and vectors (XYZ).
The Combine nodes can also be used to input single color values. For RGBA and HSVA color spaces it is recommended to use the RGB节点. Some common operations could easier be executed with the 颜色类节点.

举例¶
模糊Alpha通道示例效果。¶
In this first example, we take the Alpha channel and blur it, and then combine it back with the colors. When placed in a scene, the edges of it will blend in, instead of having a hard edge. This is almost like Anti-Aliasing but in a three-dimensional sense. Use this node setup, when adding CG elements to live action to remove any hard edges. Animating this effect on a broader scale will make the object appear to "phase" in and out, as an "out-of-phase" time-traveling sync effect.
