Possible Python Automation With This Particular Material I just had a quick question.  I am starting to get a bit more adequate with Blender in terms of getting to photorealism.  In the picture below is a model that I got online and I am wanting to edit the material for the keys to make them look more photoreal.  My question, is if there is a way of automating the material so that after I have one photoreal material on one key it will do it for the rest of the keys?  I know that I can make one material, assign that for all of the keys, and go in and change the images for each one but I feel like there is a way to automate this with python.  Any thoughts?
I would use two UV maps for each key. One is shared between all keys and maps to the key texture without letter. The second is a different UV map for each object, with one big texture containing all the key letters; having a different UV map for each key, each gets their own letter. No need to worry about the material itself then.

You can even use the UV Project modifier to project the letters on each object; no need to manually make all those UV maps.
