How to apply material to mesh in Unity

I'm attempting to apply materials to meshes in Unity 5. In the image, I have applied the same material to two different meshes. The image is wood grain and displays as desired on the right. On the left, the same material appears as solid brown. I want it to look the same as the material on the right.

The meshes are imported from Sketchup. This happens in many cases using different textures on different meshes.

I have grouped the meshes and put them in components in Sketchup, but this doesn't appear to effect the outcome.

Even on simple shapes that match approximately the height/width ratio of the image being used for the texture, this effect appears.

 

I finally solved this. I had to apply the textures to my meshes in Sketchup and then re-apply them in Unity after importing. If I create an object in Sketchup and try to apply the material in Unity, it doesn't work. But if I apply the texture in Sketchup, import it into Unity (the material will not appear on the object initially), then drag the image or material onto the object, it works as expected.
