Anyone who has used Blender for a while has probably tried to duplicate a scene via Full Copy. They would have then found that in the duplicated scene, all of the materials were duplicated as well, receiving that infuriating .001 ending. Normally, one might be able to change all the materials back to the originals and then reload the file (as suggested here) to get rid of the duplicate materials. I can do this, but I have A LOT of material slots in my project, and the work is incredibly boring.
So basically, my question is...
Is there a button, script, feature, or anything else that would disable the duplication of materials when I duplicate my scene.
Note that if the answer is a script, I will need to be walked through how to use it as my Python skills are about a -52. :)
