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.

Hi ! its amazing node but its limit is set to till 4 object indexes, what will happen if we have 50 or mode different objects in the scene and want all random index pass ?
