Of course in Blender there is Mask ID Node in the Compositor to extract IndexOB or IndexMA of a Multilayer EXR. But how to work with these passes in other compositing packages? In e.g. Nuke or After Effects there is nothing like an ID Node.

Edit: Maybe someone can tell how the passes are stored in a Multilayer EXR file?

Of course in Blender there is Mask ID Node to get this to work. But how to work with these in other compositing packages? E.g. in Nuke or After Effects there is nothing like an ID Node.

Is it still possible to iterate through these passes?
