Are there any resources or help files for using the builtin.cube? I'm trying to give a building a little texture by recessing the builtin.cube into my facade, and it works fine except for the corners where the two cubes touch each other and then disappear all together. I'm open to another way to achieve the same look. Some advise on the awnings would be nice too. They're also created with the builtin.cube then with a shed roof applied to them.
The image below is a flat, but it all looks good, just lacks some texture
You can see on the images below the faces disappear once the cube is introduced to push them back.
