Ricky, I think my addon is exactly what you’re looking for. Pick the material slot in your object materials that is the one you like. For example, it could be Mat.004 in the list Mat, Mat.001, Mat.002, etc. Then select the Material Specials menu > Clean Cad Mats and it will update all materials in all objects that use a material with the prefix Mat to the currently selected slot. It could be assigned to individual faces or the full object. It doesn’t matter.


I made this for imported cad objects. I would import an file with hundreds of bolts each with a different material. So I could have bolt_material.001 through bolt_material.965. I would find a bolt and modify the material, but then I’d have to change the material for the other 964 bolts. This lets you modify one instance of the bolt_material and then it goes through all of the objects in the scene and replaces any instance of the bolt_material with the one you just modified. The number of vertices has no effect on performance.

Edit: I’ve updated it to work with 2.80 as well.
