Tiling Floor Texture over Complex Room

madmuffin

I'm trying to get this floor texture to tile across a floor while using up the smallest amount of UV space possible. If the room was an easy shape like a cross, you could just cut the floor up into equal sized chunks and overlap them in the uv screen, but if its a non-uniform shaped room I'm not sure how to do it. Anyone encountered this before and can give me any tips?

Why do you have to limit the UV space if it's a tiling texture? Is there some technical reason for it? Normally you'd just planar map the whole floor and scale it up until you have the right number of repeats.
