Linking meshes with multiple materials

Hi, I looked at some other posts on multiple materials (on one mesh) and could not find the answer I was looking for. I am still relatively new to blender and I have a basic building that I am doing with a simple beige color and relfective blue glass for the windows. Each wall is a single mesh and I just added different materials/colors to the faces. Each wall is also separate because I have the building coming together in a simple animation. There may have been an easier way to animate it that making it all individual pieces, but it was my first animation and blender project. Anyway…

Is there an easy way to link the materials? I tried using the “Link to Object” Material pull down menu, but then it makes the next wall all reflective blue, instead of linking the multiple materials that are on the original mesh it just links the one material? I want it to link the beige wall and the blue windows on each wall, so I don’t have to edit each wall and material individually.

I am probably going about this all wrong…Could someone explain the best way to do this. It is a 20 story building with each floor being 4 indiviual walls, so I don’t want to have to do each face individually…I guess I should have planned ahead and did the window and wall materials before I duplicated the wall a bunch of times…oh well you live, you learn. I also made them single users when I was animating, so I think I lost the original link to materials and textures?

Any help would be appriciated…

If they are all the same you can just duplicate them. The materials duplicate as well. If you just want to use the same material you can choose it in the materials tab rather than recreating it for every wall. The small window with the materials’ name has a button next to it that pops up and shows all of the materials in the scene. It can be selected there. It should work even without the links made.
