   There are two sliders that affect how these tools operate:
   
   *  Radius: how big the brush is

  The terrain editor lets you create, modify, and paint terrain.

  === Changing the texture scale
  
  The field in the table to the right of the diffuse and normal textures for your texture layer is the scale. Changing that value changes the scale of the texture. +

  You will notice that the scale changes when you switch between Tri-Planar and normal texture mapping. Tri-planar mapping does not use the texture coordinates of the geometry, but real world coordinates. And because of this, in order for the texture to look the same when you switch between the two texture mapping methods, the terrain editor will automatically convert the scales for you.
  Essentially if your scale in normal texture coordinates is 16, then for tri-planar gets converted like this: 1/terrainSize/16
