    Is there a filter to set a matte based on another layers color information, like the set matte filter, only that it allows you to SAMPLE the color, (rather than limit you to Red, Green, Blue of the set matte filter)

    (yes, I am aware that I could pull a color key and use that but not as organized/easy)

    nope, I am working with CG renders and RGB mattes. Not footage. To better separate elements CG uses Red, Green, Yellow, Cyan etc. matte passes. I’d love to be able to set matte based on a SELECTED color.

    Shake, Flame can do this, wondering if there is a 3rd party filter to do this since it is a very common CG compositing task.

    ok, I am comping dozens of shots with even more layers. And handing off to other artists. I want to minimize clutter.

    I *could* dupe the RGB matte, pull a color key, put it above the layer, and set the layer below as a track matte, yes. But do this 100’s of times and ya get a lot of clutter.

    I just think a SIMPLE filter that selects a color to set a matte to based on ONE layer in a comp, rather than a drop down of a few options, would be nice.

    I love AE, but it lacks what shake, nuke, flame can do for 3D comping.
    I am hoping there is something I am not aware of in/for AE that can help with this.

    I was really asking for something specific and was clear I know the workaround. Whether something like this necessary or not is subjective.

    If anyone else has a solution, I am all ears.

    Jon Barrie had a quick tutorial where he used the color of one layer to affect the color of a text layer.

    It is under color correction > color link. There are a number of settings from averaging to darkest etc plus blending modes.

    It might be what you are after.

    cheers
