Two UV mapping Questions

1: I assume there is a way since I’ve seen it before, but how do you UV map a bump/reflection?
2: Is there displacement mapping in blender?
Thanks

To answer both questions you use the mapto pane to select how the texture influences the material properties with the mapto set on uv.
