Man UV unwrapping was not cooperating last night. As I use the latest builds just about every day I think that had a lot to do with it. Need to check out the wiki for possible documentation I was missing. Everything ended up working good but some things were just not doing what I expected.
Looks like it was not a problem with any build but some new features I was misinterpreting. This first image is of the second floor and where I had the most problems although after identifying what I had done wrong everything went smooth after that.
The next image is the beginning of part four, the interior. I did some things different from the video. In the video he gave the walls around the house the white interior material which makes these walls white inside and out. I selected all the faces and separated them from the mesh into there own object, added a solidify and added the additional material to the interior surface. Now, if I decide to move the camera angle possibly showing the sides the materials will be correct.
The big thing I did differently was the indirect lighting around the ceiling of the second floor. I created the edge loop and separated it as its own object but here I pressed ‘F’ to create one face, used the inset tool with the check box set to even and inset that face. I then deleted the inner face leaving the ledge around the periphery. When I did this I did not need to move around vertices and all edges were straight rather than angled. From then on it was solidify, add materials and everything worked perfect after that.
