Right now we can toggle a layer matte as either Alpha or Luma and a secondary option to invert.
The feature requested is to keep these options, but be able to alt + click (or some form) to cycle through the alpha/luma channels themselves.
For example, I have an RGB pass of a logo and need to create mattes out of it to isolate sections to then color correct. This requires shift channels (which will break masks) so then it'll need to be precomposed adding another layer of complexity. This would have to be done for multiple colors depending on needs.
With this new change, you'd simply be able to link a layer to the RGB pass and toggle which RGB channel you'd like to use as a alpha/luma matte. Masks would still work, no precomps needed.
It would by default cycle as alpha or luma by default, but adding in alt + click could give you the more refined matte options.
Thank you.
