In this example, the Color Key Node filters a specific green tone out of a generated Voronoi pattern and interprets it as a mask. The Node’s output color will then not contain the respective color surfaces. 在本例中,Color Key Node 从生成的 Voronoi 图案中过滤出特定的绿色色调,并将其解释为掩码。然后,Node 的输出颜色将不包含相应的颜色表面

To free image elements from the background more easily and mask them out, frequently used homogenous colors are used in the background while the photo or video material is created. If no alpha information is available, the Color Key Node can use a selected color for masking.

为了使图像元素更容易地从背景中释放出来并遮住它们,在创建照片或视频材质时,经常使用的同质颜色被用在背景中。如果没有 alpha 信息可用,则 Color Key Node 可以使用选定的颜色进行屏蔽。
