Quote - What I'm talking about is a building with say 20 props door,window,roof,beams,nails,etc. When I import the prop all the textures are there but, after spawning the props I have to go into the material room and redo all the materials. tedious...

Have you looked at BB's VSS. He used it to texture a house made from many dozens of props but loaded the shaders on them with one click. Most people use it only for skin as BB placed an excellent skin shader in the package but it's way more useful than that.
