Description:

By default Blender's Object Index passes are white only. This works fine for internal compositing but isn't very useful when you intend to do post work in an image editor (GIMP/PS).

This node group will add colours to your different pass indices (is that how you spell that?) and output the image to a file. Now when editing the final render in GIMP/PS, include this file as a layer to "select by color" the objects you'd like to isolate..

    Oh BTW if you need more explanation of render passes you can start by going here: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Passes

    and I almost forgot to mention.. this blend may appear incorrectly pre 2.62 since the mesh editing system, bmesh, has been implemented in 2.62.
