FindRecastNavigation
-------
Find the RecastNavigation include directory and library.
Use this module by invoking find_package with the form::
.. code-block:: cmake
find_package(RecastNavigation
[version] # Minimum version e.g. 1.8.0
[REQUIRED] # Fail with error if RECAST is not found
)
Imported targets
^^^^^^^^^^^^^^^^
This module defines the following :prop_tgt:`IMPORTED` targets:
.. variable:: RecastNavigation::Recast
Imported target for using the RECAST library, if found.
Result variables
^^^^^^^^^^^^^^^^
.. variable:: RECAST_FOUND
Set to true if RECAST library found, otherwise false or undefined.
.. variable:: RECAST_INCLUDE_DIRS
Paths to include directories listed in one variable for use by RECAST client.
.. variable:: RECAST_LIBRARIES
Paths to libraries to linked against to use RECAST.
.. variable:: RECAST_VERSION
The version string of RECAST found.
Cache variables
^^^^^^^^^^^^^^^
For users who wish to edit and control the module behavior, this module
reads hints about search locations from the following variables::
.. variable:: RECAST_INCLUDE_DIR
Path to RECAST include directory with ``Recast.h`` header.
.. variable:: RECAST_LIBRARY
Path to RECAST library to be linked.
NOTE: The variables above should not usually be used in CMakeLists.txt files!

/*
Debug groups allow rendering to be annotated, making debugging via APITrace/CodeXL/NSight etc. much clearer.
Because I've not thought of a quick and clean way of doing it without incurring a small performance cost,
there are no uses of this class checked in. For now, add annotations locally when you need them.
To use this class, add it to a StateSet just like any other StateAttribute. Prefer the string-only constructor.
You'll need OPENMW_DEBUG_OPENGL set to true, or shouldDebugOpenGL() redefined to just return true as otherwise
the extension function pointers won't get set up. That can maybe be cleaned up in the future.
Beware that consecutive identical debug groups (i.e. pointers match) won't always get applied due to OSG thinking
it's already applied them. Either avoid nesting the same object, add dummy groups so they're not consecutive, or
ensure the leaf group isn't identical to its parent.

do not need to render groundcover on the map, do not need to render it for the whole visible area (which can be very large with Distant Terrain). It allows to increase performance a lot.
General advices to create assets for this feature:
1. Alpha properties from Nif files are not used, a unified alpha settings are used (alpha testing, "greater of equal" function, 128/255 threshold).
2. Use a single NiTriShape in groundocver mesh, or at least use same properties (texture, alpha, material, etc), so OpenMW can merge them on the fly. Otherwise animations may not work properly.
3. Smooth fading does not work for meshes, which have textures without alpha (e.g. rock).
Groundcover mods can be registered in the openmw.cfg via "groundcover" entries instead of "content" ones:

@ -147,3 +147,14 @@ radial fog
By default, the fog becomes thicker proportionally to your distance from the clipping plane set at the clipping distance, which causes distortion at the edges of the screen.
This setting makes the fog use the actual eye point distance (or so called Euclidean distance) to calculate the fog, which makes the fog look less artificial, especially if you have a wide FOV.
Note that the rendering will act as if you have 'force shaders' option enabled with this on, which means that shaders will be used to render all objects and the terrain.
antialias alpha test
---------------------------------------
:Type: boolean
:Range: True/False
:Default: False
Convert the alpha test (cutout/punchthrough alpha) to alpha-to-coverage when :ref:`antialiasing` is on.
This allows MSAA to work with alpha-tested meshes, producing better-looking edges without pixelation.
When MSAA is off, this setting will have no visible effect, but might have a performance cost.
