Setting Houses

I have most of the terrain the way I want it at St. Leger, so now I am starting to set the houses. I have them marked on my tga file and then convert the coordinates for landscape studio (invert X and Z coordinates and then multiply by 64). Then I select an object (e.g. Pfeffer House), place it on the map, set the coordinates and then adjust the elevations.

I have a hard time understanding my position in studio, because it is almost like working in a snow storm. I usually save it, load it into the file for the game and then open up a test to see how the house is positioned. (I still have the roads marked with wheat for now.) I then decided if the object has to be rotated and then go back into studio to fix it and add any outbuildings.
