Thanks to both of you.  The consolidation of shaders thing is new to me, but I have observed it where an identical shader (named differently, usually sequentially) is assigned to similar objects in a scene.  I was fixing one shader, and applying it to the other similar material zones.  Consolidation will definitely speed this up.  Is this under the edit menu?

I agree on the concept of a universal bump change.  I think it could be a universal percentage, or a percentage of the current value (say 10% of 500%, yielding 50%).  In some situations applying this to all shaders would be less disruptive than setting all to one fixed number.  Either way, one would have to do a lot of manual tweaking anyway.

Thanks again - anyone else have any tips on fixing shaders?
