-====== Graphic Module ======+====== Description ======
 The **height** texture property defines the height of the surface. This allows Graphic Modules to improve lighting by taking small scale elevations on the surface into account. The **height** texture property defines the height of the surface. This allows Graphic Modules to improve lighting by taking small scale elevations on the surface into account.
  
-The source is typically an 8 bit image with 1 color components inside the range from 0 to 1. 0 represents a point located at the lowest point underneath the surface. 0.5 represents a point on the surface. 1 represents a point located at the highest point above the surface. Using high definition range images values beyond can be used as well.+This is also a special texture property similar to the normal map one but this time the height of a surface relative to the mesh surface is stored. This height can be used for different purpose depending on the graphic module used. One usage is to derive a normal map from the height difference. Another usage is to dynamically increase the detail level of a mesh. The new vertices are then offset using this height. Terrain meshes can also use this height information to provide LODing (level of detail reduction over distance).
  
-The default value for this texture property is 0.5 .+A value of 0.5 indicates no surface height alteration. Values below 0.5 indicate a dent in a surface while values above 0.5 indicate a bump in a surface. The strength and offset of the height alteration can be set using the [[gamedev:textureproperties:height_scale|height.scale]] and [[gamedev:textureproperties:height_scale|height.offset]] property.
  
-====== Physics Module ====== +The source is typically an 8 bit image with 1 color components inside the range from 0 to 1. 0 represents a point located at the lowest point underneath the surface. 0.5 represents a point on the surface. 1 represents a point located at the highest point above the surface. Using high definition range images values beyond can be used as well.
-This texture property does not effect Physics Modules.+
  
-====== Audio Module ====== +The default value for this texture property is 0.5 .
-This texture property does not effect Audio Modules.+
