Smart UV Project: the sequence of the faces is wrong and has inconsistent width I’m new to Blender, been using it less than a month. I created a small tower, and am now trying to apply a texture. 

My issue is in the Unwrapping, I get the best result from Smart UV Project. When it unwraps however the sequence of the faces is wrong and the width of the face panels in the UV/Image Editor are incorrect. It makes my seamless texture not so seamless. 

Scale is set to 1.000 for X,Y &amp; Z. The doors and windows were created using a Boolean Modifier.

Unwrapped Cylinder


So how do I go about unwrapping it in order and scaled correctly? Any help solving this would be greatly appreciated.
I think you can work a bit on this: I tried with your file and got some decent result, imho.

The first thing is: I isolated just the exterior walls.



then I set the front view and unwrapped cylindrical



I got an (extremely high) quite nice square unwrap



but helping with 2d cursor and the pivot choice, it's easy to scale it dow to make it a bit more manageable







then I loaded a brick wall image similar to yours



and aligned and scaled the uv map to the image

what about the face sequence? it seems ok, look them while I select (in top view) all faces...



Hth..
