+If set above ``0.0`` (exclusive), blends between the fog's color and the color of the background :ref:`Sky<class_Sky>`, as read from the radiance cubemap.

 This is useful to simulate `aerial perspective <https://en.wikipedia.org/wiki/Aerial_perspective>`__ in large scenes with low density fog. However, it is not very useful for high-density fog, as the sky will shine through. When set to ``1.0``, the fog color comes completely from the :ref:`Sky<class_Sky>`. If set to ``0.0``, aerial perspective is disabled.
 
+Notice that this does not sample the :ref:`Sky<class_Sky>` directly, but rather the radiance cubemap. The cubemap is sampled at a mipmap level depending on the depth of the rendered pixel; the farther away, the higher the resolution of the sampled mipmap. This results in the actual color being a blurred version of the sky, with more blur closer to the camera. The highest mipmap resolution is used at a depth of :ref:`Camera3D.far<class_Camera3D_property_far>`.

@@ -19,7 +19,7 @@ Description
 
 An array specifically designed to hold :ref:`Vector2<class_Vector2>`. Packs data tightly, so it saves memory for large array sizes.
 
-\ **Differences between packed arrays, typed arrays, and untyped arrays:** Packed arrays are generally faster to iterate on and modify compared to a typed array of the same type (e.g. :ref:`PackedVector3Array<class_PackedVector3Array>` versus ``Array[Vector2]``). Also, packed arrays consume less memory. As a downside, packed arrays are less flexible as they don't offer as many convenience methods such as :ref:`Array.map<class_Array_method_map>`. Typed arrays are in turn faster to iterate on and modify than untyped arrays.

 \ **Note:** Packed arrays are always passed by reference. To get a copy of an array that can be modified independently of the original array, use :ref:`duplicate<class_PackedVector2Array_method_duplicate>`. This is *not* the case for built-in properties and methods. The returned packed array of these are a copies, and changing it will *not* affect the original value. To update a built-in property you need to modify the returned array, and then assign it to the property again.
