Nathan - Unfortunately, there's no way that I know of to set up a universal scale for tiling a shader. If you have four walls, each one being a seperate object, you're going to have to figure the vertical and horizontal repeat value for each object to result in same-scale bricks or stones. The only work-around I can think of would be to group all the objects that are made of the single shader, export the group as a single object (in a DXF or OBJ or some other format). Then, re-import the object into the RDS scene and apply the shader to the new object; it will apply to all the formerly seperate elements. Of course, if your elements are walls of the building, the 30 by 30 tiling option might be inadequate; you may need to build your texture maps larger. I'm a little foggy this morning (out too late last night), so if this doesn't make any sense, let me know; maybe later I can be clearer later in the day. But I hope it helps. - Dex
