This script is a toolbox.
A collection of tools, intended mainly to help you manipulating scenes imported from other 3d softwares, such as Rhino, Sketchup, etc. The Condensers attach objects by its material or layer and rename the resulting object as its material/layer. You can also optimize the resulting geometry. The other tools do pretty much what you expect, according to its name and options. I hope this tool is as useful to you as for me.
v1.01 - Fixed issue in Condense by Layer when processing the last created layer.
