hello synchromesh
in sketchup is very simple, you just have the skin of the model and then you can manage every single face. You have to apply the texture with the paint bucket tool and then clicking with the right mouse button on each side and select "texture". At this point, you can stretch, scale, distort, move the texture. a job is a bit long but it works. I'm looking for a plugin to do the texturebaking
I modeled this building with sketchup and applied a single texture
