I actually made this one a while ago now. We're supposed to be mass-producing 3D artefacts of this sort every week for the masters I'm currently doing. All the textures are from cgtextures.com. I haven't had time to edit them extensively (as you can see from the tiling at either end of the roof).

Interestingly, the lighting seemed to look better without the roof, and so that's how I decided to bake it. You might notice that there's no discernible light source from which to cast the shadows.

It took me about a day to do. I'm quite pleased with my current workflow and hope to upload more content in the future, along with tutorials.

If anyone's interested, I lightmapped the scene with lightup and have written a tutorial on the process. You can read it here.

If you have the Unity 3D plugin installed, you can walk around the scene here.
