Hey Gerbrand, You can save each extra image plane into their own file by setting the `Different File` parameter. Note that this parameter is hidden when the `Output Picture` parameter is set to the default value of `ip`, so just change it to point to an actual file on disk. If you then want to save the image planes directly into the RGB channels, then you can set the `Channel Name` parameter to `C` but this won't always be an answer to your problems if you decide for example to export the image planes for each component and/or each light. So you'd better find a solution for After Effects. In Nuke, the `Shuffle` node doest just that.
For the mattes, you have many ways but one that I dig is to use the `Forced Matte` parameter, under the `Objects` tab of the Mantra node. This way, if you'd like to split the render for different sets of objects, then you could for example create a bundle named `@objects` that would contain all the objects to render and, in the Mantra node dedicated to render your specific object `OBJECT_SPHERE`, you could set `@objects ^OBJECT_SPHERE` in the `Forced Matte` parameter to define every rendered object of your scene as matte but the current object that you want to render. I find it to be quite a flexible approach knowing that you can create smart bundles based on name patterns such as `/obj/OBJECT_%`. In other words, this means that you possibly have nothing to worry about if you decide later on to add more objects into your scene—your matte for the sphere object will still work.
