Often the linden homes exterior textures are incomplete... some walls have the color but not the texture, while others have the texture. This happens a lot whether we use the default exterior or a texture shell over it. I have enclosed two pictures... one shows the linden home with default house texture (blue) with both the mobile and viewer images. The other shows another example where a texture shell is used... that one just has two pictures of the mobile and none from the regular viewer.
