Textures
  
       
  Textures can be applied to entire brushes or to individual polygons. Until you apply a texture to it, the brush or polygon is only geometry and will not have a visual appearance when your world is compiled and played.

Take the following steps to apply a texture.
  1. Display the Texture tab in the Project Window.
  2. Select the appropriate textures directory in the upper pane.
  3. Select the desired texture in the middle pane.
  4. In one of the view panes, select the desired brush or polygon. Or display the Nodes Tab and make your selection there. You can also select multiple nodes.

Click Apply Texture [Apply Texture Button] on the WorldEdit toolbar.

If the texture does not appear in the Perspective View pane, assure that you are in Textured Polies shading mode as described in the Views section.

Hint: If you select the node before you select the texture, you must return focus to the World Editing window before clicking Apply Texture. Do so by clicking once in any view pane.
