Texture Mapping

I think I’m losing my mind. I have tried to find help with my issue everywhere and I’m exhausted and with no solution. I hope someone here can help.

I’ve created a polygon model of a house in Maya 2008. Now that I’m done modeling I want to apply some textures to the outer walls. I have a 512 X 512 seamless brick texture image I want to use. I create a new Lambert object and assign the image file to it. I then select all the faces on the outside walls and then right click the Lambert material and choose “assign material to selection”. On my model some of the faces have the brick image zoomed in and others have it zoomed out, it’s all a mess. If I open the UV texture editor I see where it’s placed all the mappings in crazy places with crazy sizes, all on top of each other. In that texture editor I tried to resize some of the mappings or move them and it won’t let me. I was able to create a new map and even though it only contains the faces I selected - I still cannot edit their position or size.

Why does this have to be so complicated? And further more how can I fix it? I looked for tutorials and tips but most of them are geared towards creating planar, cylinder mappings but I can’t use these as my walls go all the way around the building.

Help?
