A simple script to doc the object Index value :
http://jmsoler.free.fr/didacticiel/blender/tutor/bpy_object_passIndex.htm
in french but with a lot of picture.
Updated : an internal menu was added and also the header for the blender scripts’ menu.
probably best to use ob.matrixWorld.locationPart() rather then loc, since loc dosnt take parents of constraints into account.
Probalbly. I will try.
Thanks for the advise.
