- [Instructor] SketchUp faces have a front side and a backside. The backside is blue by default, and the front side is white. When a shape is pulled up, like this, the face orientation should result in outwards-facing white faces, and inside of the shape, we can see that it's blue. That's the correct face orientation. But every once in a while, an extruded shape does not result in outward-facing white faces and inward-facing blue faces, like this one. It's reversed. As we model, it's important to keep an eye on these and fix them as the need arises. This becomes especially important when you start using photo-realistic rendering plugins, as they won't render properly if the texture is applied to a backward face that is improperly oriented. So to fix this, with this cube, all of the faces that are connected to the cube are blue. So I can simply triple click, one, two, three, to select all of this connected geometry, and then right click, reverse faces. With this last cube though, we have a few blue faces and a few white faces. So a triple click, reverse face would just result in a flip-flopping of the blue and the white faces. So instead, I'll choose a face that is properly oriented, like this one on the end, right click, and use that as a template for the rest of the cube. I can choose the option orient faces. And now all of the other faces that are connected should reorient themselves to a white, outward-facing face. Again, it's a good idea to keep an eye on anything backwards-facing so that you can fix it as it appears.
