Building with cubes in UDK
Note: you can also use BSP brushes to do this. That is probably more efficient in resource consumption. Using a mesh like in this example gives the building a slight minecraft look.
First I created a cube in blender and brought it into UDK.
A few notes about the cube:
1. I used the default cube in blender. no size adjustments
2. export size = 48. The cube perfectly aligns with other cubes in UDK with a grid snap of 16.
3. I added collision
4. I took the time to perfectly lightmap the cube using as much of the light map as possible
Within UDK I set the light map resolution to 128 on cube.
I then created a copy of the cube for every seamless texture I had.
This was the result:
Using these cubes and a few other meshes (tree, grass, stacks logo) I built this house in 2 hours:
If you look carefully you will see dark seams at the edges of each block. This is due to the light map surfaces bleeding onto other surfaces. I could fix that but I like the look of that so I left it alone.

That was a lot of fun. I will be doing a demo of my game to my daughter's class in a few weeks. I will show them this house of an example of how to build something quickly.
