And this is me (in my new T-shirt), showing you the improvement a texturemap can make. Yes, it's the one above.

What you have to do is tile the texturemap, and adjust the U and V scales to suit. Using the UV map I'v made for the garage, the V-scale is about 0.1420 and the U-scale is 0.07150

I shall have to measure a brick, make a block, and use it a gauge.

Tweak the V-offset to get a mortar-line matching the top edge of the doors. On a real brick building, the wall goes into the ground, but builders don't like untidy tops to doors.

And now back to the Doc...
