合并/分离节点¶
这类节点本质上都是做同一件事情:
分离:将一幅图像的颜色通道分离成单独颜色通道。
合成:将单独的颜色通道 重新/合成 为单一的混合颜色通道。
These nodes can be used to manipulate each color channel independently. Each type is differentiated in the applied Color Space.
在合成和相关的贴图中都支持Alpha通道。在贴图的中只允许使用RGB色彩空间。在Blender内部着色器节点的HSV或Cycles 着色器都提供了额外的可以 合并/分离 矢量(XYZ)的节点。
合成节点也可以用于输入单独的颜色值。在RGBA和HSVA颜色空间推荐使用 RGB节点。一些简单的操作可以通过 颜色类节点 来实现。

范例¶
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.
