It is recommended to configure the settings and order of shaders through the in game HUD. By default this is available with the F2 key.
|
||||
Note, an empty chain will not disable post processing.
|
||||
|

|
||||
|
||||
Use for eye adaptation to control speed at which average scene luminance can change from one frame to the next.
|
||||
Average scene luminance is used in some shader effects for features such as dynamic eye adaptation.
|
||||
Smaller values will cause slower changes in scene luminance. This is most impactful when the brightness
|
||||
drastically changes quickly, like when entering a dark cave or exiting an interior and looking into a bright sun.
|
||||
|
||||
This settings has no effect when HDR is disabled or :ref:`enabled` is set to false.

transparent postpass

|

:Type: boolean
|
||||
:Range: True/False
|
||||
:Default: True
|
||||
|
||||
Re-renders transparent objects with alpha-clipping forced with a fixed threshold. This is particularly important with vanilla content, where blended
|
||||
objects usually have depth writes disabled and massive margins between the geometry and texture alpha.
|
||||
|
||||
|
||||
.. warning::
|
||||
This can be quite costly with vanilla assets. For best performance it is recommended to use a mod replacer which
|
||||
uses alpha tested foliage and disable this setting. Morrowind Optimizaton Patch is a great option.
|
||||
If you are not using any shaders which utilize the depth buffer this setting should be disabled.

#########################
|

|
||||
Overview
|
||||
########
|
||||
|
||||
Shaders are written in a OpenMW specific ``*.omwfx`` format. This is a light
|
||||
wrapper around GLSL, so a basic understanding of GLSL should be acquired before
|
||||
attempting to write any shaders. Every shader must be contained within a single
|
||||
``*.omwfx`` file, ``#include`` directives are currently unsupported.
|
||||
|
||||
By default, all shaders only guarantee support of GLSL 120 features. To target a
|
||||
newer GLSL version, you must specify it in the `technique`_ block properties. If
|
||||
the specified version is not supported on the target machine, the shader will
|
||||
not load.
|
||||
|
||||
Reserved Keywords
|
||||
#################
|
||||
|
||||
GLSL doesn't support namespaces, instead reserved prefixes are used. Do not
|
||||
attempt to name anything starting with ``_`` or ``omw``, this will cause
|
||||
name clashes.
|
||||
|
||||
|
||||
Builtin Samplers

|
||||
+------------------+---------------------------+---------------------------------------------+
|
||||
|
||||
These are included in a common header in every pass, they do not need to be re-defined.
|
||||
It is recommended to use the accessor functions to retrieve the sampler value.
|
||||
OpenMW supports multiview rendering, so these samplers will either be a
|
||||
``sampler2D`` or ``sampler2DArray``. If you want more control over how you
|
||||
sample textures, use the ``OMW_MULTIVIEW`` macro to determine the appropriate functions to use.

Blocks
|
||||
######
|
||||
|
||||
``fragment``
|
||||
*************
|
||||
|
||||
Declare your passes with ``fragment`` followed by a unique name. We will define the order of these passes later on.
|
||||
Each ``fragment`` block must contain valid GLSL. Below is a simple example of defining two passes.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
fragment pass {
|
||||
void main()
|
||||
{
|
||||
omw_FragColor = vec4(1.0);
|
||||
}
|
||||
}
|
||||
|
||||
fragment otherPass {
|
||||
|
||||
omw_In vec2 omw_TexCoord;
|
||||
|
||||
void main()
|
||||
{
|
||||
omw_FragColor = omw_GetLastPass(omw_TexCoord);
|
||||
}
|
||||
}
|
||||
|
||||
``vertex``
|
||||
***********
|
||||
|
||||
For every ``fragment`` block you declare, OpenMW generates a default vertex shader if you do not define one. This is used to draw the fullscreen triangle used in postprocessing.
|
||||
This means you rarely need to use a custom vertex shader. Using a vertex shader can sometimes be useful when you need to do lots of complicated calculations that don't rely on pixel location.
|
||||
The vertex shader only invocates on the `3` vertices of the fullscreen triangle.
|
||||
Below is an example of passing a value through a custom vertex shader to the fragment shader.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
vertex pass {
|
||||
#if OMW_USE_BINDINGS
|
||||
omw_In vec2 omw_Vertex;
|
||||
#endif
|
||||
|
||||
uniform sampler2D noiseSampler;
|
||||
|
||||
omw_Out vec2 omw_TexCoord;
|
||||
|
||||
// custom output from vertex shader
|
||||
omw_Out float noise;
|
||||
|
||||
void main()
|
||||
{
|
||||
omw_Position = vec4(omw_Vertex.xy, 0.0, 1.0);
|
||||
omw_TexCoord = omw_Position.xy * 0.5 + 0.5;
|
||||
|
||||
noise = sqrt(omw_Texture2D(noiseSampler, vec2(0.5, 0.5)).r);
|
||||
}
|
||||
}
|
||||
|
||||
fragment pass {
|
||||
omw_Out vec2 omw_TexCoord;
|
||||
|
||||
// our custom output from the vertex shader is available
|
||||
omw_Out float noise;
|
||||
|
||||
void main()
|
||||
{
|
||||
omw_FragColor = vec4(1.0);
|
||||
}
|
||||
}
|
||||
|
||||
|
||||
``technique``
|
||||
*************
|
||||
|
||||
Exactly one ``technique`` block is required for every shader file. In this we define important traits like author, description, requirements, and flags.

| flags | `SHADER_FLAG`_ | ``,`` separated list of shader flags |
|
||||
+------------------+--------------------+---------------------------------------------------+
|
||||
|
||||
In the code snippet below, a shader is defined that requires GLSL `330`, HDR capatiblities, and is only enabled underwater in exteriors.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
fragment dummy {
|
||||
void main()
|
||||
{
|
||||
omw_FragColor = vec4(0.0);
|

}
|

}
|

|
||||
technique {
|

passes = dummy;
|

glsl_version = 330;
|
||||
hdr = true;
|

flags = disable_interiors | disable_abovewater;
|

}
|
||||
|
||||
|
||||
``sampler_*``
|
||||
*************
|
||||
|
||||
Any texture in the VFS can be loaded by a shader. All passes within the technique will have access to this texture as a sampler.
|
||||
OpenMW currently supports ``1D``, ``2D``, and ``3D`` texture samplers, cubemaps can not yet be loaded.
|
||||

|
||||
|
||||
The properites for a ``sampler_*`` block are as following.
|
||||
The only required property for a texture is its ``source``.

In the code snippet below, a simple noise texture is loaded with nearest filtering.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
sampler_2d noise {
|
||||
source = "textures/noise.png";
|
||||
mag_filter = nearest;
|
||||
min_filter = nearest;
|
||||
}
|
||||
|
||||
To use the sampler, define the appropriately named `sampler2D` in any of your passes.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
fragment pass {
|
||||
omw_In vec2 omw_TexCoord;
|
||||
|
||||
uniform sampler2D noise;
|
||||
|
||||
void main()
|
||||
{
|
||||
// ...
|
||||
vec4 noise = omw_Texture2D(noise, omw_TexCoord);
|
||||
}
|
||||
}
|
||||
|
||||
``uniform_*``
|
||||
**************
|
||||
|
||||
It is possible to define settings for your shaders that can be adjusted by either users or a Lua script.

The ``description`` field is used to display a toolip when viewed in the in-game HUD. The ``header`` field
|
||||
field can be used to organize uniforms into groups in the HUD.
|
||||
|
||||
If you would like a uniform to be adjustable with Lua API you `must` set ``static = false;``. Doing this
|
||||
will also remove the uniform from the players HUD.
|
||||
|
||||
Below is an example of declaring a ``vec3`` uniform.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
uniform_vec3 uColor {
|
||||
default = vec3(0,1,1);
|
||||
min = vec3(0,0,0);
|
||||
max = vec3(1,1,1);
|
||||
step = vec3(0.1, 0.1, 0.1);
|
||||
description = "Color uniform";
|
||||
static = true;
|
||||
header = "Colors";
|
||||
}
|
||||
|
||||
To use the uniform you can reference it in any pass, it should **not** be declared with the ``uniform`` keyword.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
fragment pass {
|
||||
void main()
|
||||
{
|
||||
// ...
|
||||
vec3 color = uColor;
|
||||
}
|
||||
}
|
||||
|
||||
|
||||
``render_target``
|
||||
*****************
|
||||
|
||||
Normally when defining passes, OpenMW will take care of setting up all of the render targets. Sometimes, this behavior
|
||||
is not wanted and you want a custom render target.

|

+------------------+---------------------+-----------------------------------------------------------------------------+
|
||||
|
||||
|
||||
To use the render target you must assign passes to it, along with any optional clear modes or custom blend modes.
|
||||
|
||||
In the code snippet below a rendertarget is used to draw the red cannel of a scene at half resolution.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
render_target RT_Downsample {
|
||||
width_ratio = 0.5;
|
||||
height_ratio = 0.5;
|
||||
internal_format = r16f;
|
||||
source_type = float;
|
||||
source_format = red;
|
||||
}
|
||||
|
||||
fragment downsample2x(target=RT_Downsample) {
|
||||
|
||||
omw_In vec2 omw_TexCoord;
|
||||
|
||||
void main()
|
||||
{
|
||||
omw_FragColor.r = omw_GetLastShader(omw_TexCoord).r;
|
||||
}
|
||||
}
|
||||
|
||||
Now, if we ever run the `downsample2x` pass it will write to the target buffer instead of the default
|
||||
one assigned by the engine.
|
||||
|
||||
To use the uniform you can reference it in any pass, it should **not** be declared with the ``uniform`` keyword.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
fragment pass {
|
||||
void main()
|
||||
{
|
||||
// ...
|
||||
vec3 color = uColor;
|
||||
}
|
||||
}
|
||||
|
||||
Simple Example
|
||||
##############
|
||||
|
||||
Let us go through a simple example in which we apply a simple desaturation
|
||||
filter with a user-configurable factor.
|
||||
|
||||
Our first step is defining our user-configurable variable. In this case all we
|
||||
want is a normalized value between 0 and 1 to influence the amount of
|
||||
desaturation to apply to the scene. Here we setup a new variable of type
|
||||
``float``, define a few basic properties, and give it a tooltip description.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
uniform_float uDesaturationFactor {
|
||||
default = 0.5;
|
||||
min = 0.0;
|
||||
max = 1.0;
|
||||
step = 0.05;
|
||||
static = true;
|
||||
description = "Desaturation factor. A value of 1.0 is full grayscale.";
|
||||
}
|
||||
|
||||
Now, we can setup our first pass. Remember a pass is just a pixel shader invocation.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
fragment desaturate {
|
||||
omw_In vec2 omw_TexCoord;
|
||||
|
||||
void main()
|
||||
{
|
||||
// fetch scene texture from last shader
|
||||
vec4 scene = omw_GetLastShader(omw_TexCoord);
|
||||
|
||||
// desaturate RGB component
|
||||
const vec3 luminance = vec3(0.299, 0.587, 0.144);
|
||||
float gray = dot(luminance, scene.rgb);
|
||||
|
||||
omw_FragColor = vec4(mix(scene.rgb, vec3(gray), uDesaturationFactor), scene.a);
|
||||
}
|
||||
}
|
||||
|
||||
Next we can define our ``technique`` block, which is in charge of glueing
|
||||
together passes, setting up metadata, and setting up various flags.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
technique {
|
||||
description = "Desaturates scene";
|
||||
passes = desaturate;
|
||||
version = "1.0";
|
||||
author = "Fargoth";
|
||||
passes = desaturate;
|
||||
}
|
||||
|
||||
|
||||
Putting it all together we have this simple shader.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
uniform_float uDesaturationFactor {
|
||||
default = 0.5;
|
||||
min = 0.0;
|
||||
max = 1.0;
|
||||
step = 0.05;
|
||||
description = "Desaturation factor. A value of 1.0 is full grayscale.";
|
||||
}
|
||||
|
||||
fragment desaturate {
|
||||
omw_In vec2 omw_TexCoord;
|
||||
|
||||
void main()
|
||||
{
|
||||
// fetch scene texture from last shader
|
||||
vec4 scene = omw_GetLastShader(omw_TexCoord);
|
||||
|
||||
// desaturate RGB component
|
||||
const vec3 luminance = vec3(0.299, 0.587, 0.144);
|
||||
float gray = dot(luminance, scene.rgb);
|
||||
|
||||
omw_FragColor = vec4(mix(scene.rgb, vec3(gray), uDesaturationFactor), scene.a);
|
||||
}
|
||||
}
|
||||
|
||||
technique {
|
||||
description = "Desaturates scene";
|
||||
passes = desaturate;
|
||||
version = "1.0";
|
||||
author = "Fargoth";
|
||||
passes = desaturate;
|
||||
}

Overview of Post Processing Framework
|
||||
#####################################
|
||||
|
||||
Overview
|
||||
========
|
||||
|
||||
OpenMW supports a moddable post process framework for creating and
|
||||
controlling screenspace effects. This is integrated into OpenMW's Lua API, see
|
||||
`reference <../lua-scripting/openmw_shader.html>`_ for details.
|
||||
|
||||
Basic concepts
|
||||
==============
|
||||
|
||||
Pass
|
||||
Describes a single shader invocation pass. Currently only pixel (also known
|
||||
as fragment) shaders are supported.
|
||||
|
||||
Technique/Shader
|
||||
An ordered list of passes, techniques will encompass a single effect like
|
||||
bloom or SSAO. Technique is interchangable with shader.
|
||||
|
||||
Installing and Activating
|
||||
=========================
|
||||
|
||||
Shaders are managed through the virtual file system, simply install the associated
|
||||
archive or folder as described in :ref:`mod-install<install>`. Shaders must be
|
||||
in the `Shaders` directory to be discoverable. A shader can be activated in one
|
||||
of two ways:
|
||||
|
||||
1. Adding the shaders filename (without its extension) to the end of the
|
||||
:ref:`chain` list in ``settings.cfg``.
|
||||
2. Using the in game post processor HUD, which can be activated with the ``F2``
|
||||
key by default. This is the recommended method as manual editing can be error
|
||||
prone.
|
||||
|
||||
Hot Reloading
|
||||
==============
|
||||
|
||||
It is possible to modify a shader without restarting OpenMW, :ref:`live reload`
|
||||
must be enabled in ``settings.cfg``. Whenever a file is modified and saved, the
|
||||
shader will automatically reload in game. This allows shaders to be written in a
|
||||
text editor you are comfortable with. The only restriction is that new shaders
|
||||
cannot be added, as the VFS will not be rebuilt and OpenMW will not be aware of
|
||||
the new file.
|
||||
Some files were not shown because too many files have changed in this diff Show More
