No textures when using .fxb files

I exported the files from Google Sketchup Pro 8 as .fxb with “Export two-sided faces” and “Triangulate all faces” checked off (with a few other checked off in the other sections), I’ve imported all kinds of meshes in Unity 3d, but I never get any textures on them.

PS: Does anybody know how to turn colliding with other items on, so I can’t walk through the walls.

Are you placing the texture in the in unity also? when i export i save out as a .FBX then i drag and drop then go and get the texture and place in a folder i have for it in unity then just select the object and drag the texture on to it.
