Materials Not Working

Can anyone tell me why my materials are not working?

  1. Simple texture.
  • I dragged in the jpeg grass
  • I converted it to a New Material
  • I clicked Apply
    When I drag it to the landscape, nothing happens.
  1. Blending Materials
  • I created a new blank Material
  • I imported my Landscape Coordinants and my Landscape Blend
  • I imported my grass and dirt jpegs
  • I set my Blend layers
    Connected everything up as per below, and the ball is black and nothing works.
