|The tool loads in all materials of the file instances, which it converts, and indexes the loaded materials
to achieve unique names. The tool does this to avoid material name conflicts. For example, a converted file
instance of a window object can include a material called 'glass' with regular glass properties, and another
converted file instance of a wine glass may include another kind of glass material, with the same name but
with a higher refraction index (crystal glass). Both object use the correct glass after conversion.
