Even if you may find a few users here that knows Blender, I guess you'll get faster some information on a Blender forum.
By the way, even if I know the photo creation tool isn't perfect, why do you prefer to try with Blender?

I tried the PhotoCreation tool, but it does not work (the preview pane is empty, although the 3D view is ok and the "normal" photo creation works).

The quality of the Blender-rendered pictures is amazing, so of course I would like to see what my own house will look like (especially when trying out different textures for walls and floors...)

Still hoping
