this node is a simplified version of nukes shuffle node. the integer slider is dynamic and will always show the number of available layers. the selected layer will always be shuffled into rgba.
Colormatte can be used to extract different part from a color pass with the help of rgb pass.
If you have a CG rendered with a colored BG and not Black you will get and edge issue with regular Premult. But with this ColorPremult Gizmo it will solve the edge and Semi-Transparency issue save you time as you don't have to re-render you image with black background. Hope this helps. Thanks Kundan
Extract Coverage Pass from render in Arnold & Renderman

Offset Channels, Huecorrect them and mask only the areas you want to get affected by the effect with a mask.
Simple but nice and useful Depth Keyer
If you are using any rendering program that can output rendered images with separated light passes as channels, you can use this mixer for all the light passes. You can list all the channels you wan't to exclude. Some defaults already listed.
A combination of Shuffle nodes to return an alpha channel with Stencil and Mask integrated!
Merge all your alpha using one groupe instead of lots of channelMerge nodes.
