| 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 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). | ||

| + | 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: | ||
| 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. | 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.
