Derive Node Reference
Channel Mask Node
Description
The Channel Mask node creates an output that is composed only of selected color channels. Channels can be cancelled out from the input this way. This node is most commonly used to extract data from textures that is otherwise obscured. The same result can be produced by using Channel Breakup node and appending individual channels using an Append node.
