For some reason some of my materials and textures aren't rendering when I do a full render (or even in the render viewport). I've attached an image below to demonstrate. Notice the front window frame and shutters are not rendering much texture at all. When I select the object in the viewport, all of a sudden the material renders. If I deselect, it goes back to the default gray.
Thanks for your help!
EDIT I'm thinking it has something to do with these objects being "alt-D" duplicated instead of "shift-D". Could this be?
