[help] Is there a separate RGB node equivalent?

[ivanebeoulve]

the node im talking about in cycles separates an image file's color to their RGB channels, this node is widely used to create mask textures using the 3 channels as 3 different mask in gaming and in this particular case Im trying to use it to separate a tension map stored in vertex colors.

im hoping to find a node or a process that gives me a similar result.

EDIT: found the Color Chanel node but cant get it to work at all, maybe a bug?

You can use the "Color Operations" node.
