+Bent normal map
+---------------
+
+A bent normal map describes the average direction of ambient lighting. Unlike a
+regular normal map, this is used to improve how a material reacts to lighting
+rather than add surface detail.
+
+This is achieved in two ways:
+
+* Indirect diffuse lighting is made to match global illumination more closely.
+* If specular occlusion is enabled, it is calculated using the bent normals and
+  ambient occlusion instead of just from ambient light.
+  This includes screen-space ambient occlusion (SSAO) and other sources of
+  ambient occlusion.
+
+.. image:: img/spatial_material_bentnormals.webp
+
+Godot only uses the red and green channels of a bent normal map for better
+compression and wider compatibility.
+
+When creating a bent normal map, there are three things required for it to
+work correctly in Godot:
+
+* A **cosine distribution** of rays has to be used when baking.
+* The texture must be created in **tangent space**.
+* The bent normal map needs to use the X+, Y+, and Z+ coordinates, this is
+  known as OpenGL style. If you've imported a material made to be used with
+  another engine it may be DirectX style, in which case the bent normal map
+  needs to be converted so its Y axis is flipped. This can be achieved by
+  setting the green channel under the **Channel Remap** section to
+  **Inverted Green** in the import dock.
+
+.. note::
+
+  A bent normal map is different from a regular normal map. The two are not
+  interchangeable.
