+= Bump Mapping =
+To use a bump map in a material, you can create a new material script inheriting from the base bump map script. Replace both texture image files with your own files.
+
+{{{#!cpp
+import * from "BumpMap.material"
+// Any number of lights, diffuse
+material Cube_Lava_Normal : BumpMap_Base
+{
+    technique
+    {
+        pass ambient
+        {
+        }
+        // Now do the lighting pass
+        // NB we don't do decal texture here because this is repeated per light
+        pass perlight
+        {
+            // Base bump map
+            texture_unit normalmap
+            {
+                texture Cube_Lava_NORM.jpg
+                colour_op replace
+            }
+        }
+
+        // Decal pass
+        pass decal
+        {
+            texture_unit decalmap
+            {
+                texture Cube_Lava_COLOR.jpg
+            }
+        }
+    }
+}
+}}}
+
+The base bump map material script is located at `[media_directory]/materials/BumpMapping/BumpMap.material`
+
+To get an idea what bump maps are capable of, start the test level `BumpMap`
