I wrote this tool as the one at Dneg seems to have stopped working. I couldn't puiblish the model until I had unique names for all objects. This is because it can get messy otherwise in Clarisse when doing shader assignment rules.

 

This isn't very complicated really, but requires filtering of items in a list as as I couldn't find a method / command to select only group nodes. Group nodes are seen as transforms and so when selecting all transforms it shall select the ones attached to the mesh shape of an object.

This script finds the shortest unique name for each object and renames it to that. It then adds _grp to the end of every group node, as its removed from everything to clean out the geo/mesh naming.
