+Sampling Bias
+=============
+
+Normal Bias
+   Offset sampling of the irradiance grid in the surface normal direction to reduce light bleeding.
+   Can lead to specular appearance of diffuse surface if set too high.
+
+View Bias
+   Offset sampling of the irradiance grid in the viewing direction to reduce light bleeding.
+   Can lead to view dependant result if set too high. Prefer this if camera is static.
+
+Facing Bias
+   When set to zero, avoids capturing points behind the shaded surface to bleed light onto
+   the shaded surface. This produces non-smooth interpolation when the capture resolution is high.
+   Increasing this bias will make the interpolation smoother but also introduce some light bleeding.
+
+
+Validity & Dilation
+===================
+
+During the baking process, a validity score is assigned to each capture point.
+This score is based on the number of back-faces hit when capturing the incoming lighting.
+Only materials with *Single Sided* turned on for Light Probe Volumes will reduce the validity score.

+Bake
+====
+
+Light probe volume light data is static and needs to be manually baked.
+Once baked, the data is stored inside the object data-block and can be moved, animated and linked
+between blender files.
+
+.. note::
+   Baking uses the render visibility of the objects in the scene.
+
+During baking, the scene is converted into a different representation to accelerate light transport.
+This representation can be very memory intensive and prevents baking if it cannot fit inside the GPU memory.
+There are a few way to deal with this issue:
+- Larger scenes should be divided into smaller sections or use different level of details.
+- Reduce *Surfel Resolution*.
+- Turn off the light probe volume visibility option on objects that have little to no effect in the bake.
+
+.. tip::
+
+   The internal scene representation can be inspected using the `Debug Value` 3, 4 and 5.
+
+Resolution
+   Spatial resolution for volumetric light probes is determined per probe.
+   The local volume is divided into a regular grid of the specified dimensions.
+   The lighting will be captured for each cell in this grid.
+
+Bake Samples
+   Number of ray directions to evaluate when baking.
+   This increases the baking time proportionally to the size of the scene representation.
+
+Surfel Resolution
+   Number of surfels to spawn in one local unit distance.
+   Higher values increase quality, but have a huge impact on memory usage.
+
+   .. tip::
+      A good value is twice the maximum *Resolution*.
+
+
+Capture
+=======
+
+Capture Distance
+   Distance around the light probe volume that will be captured during the bake.
+   A distance of 0 will only considered the inside of the volume.
+
+World Contribution
+   Bake incoming light from the world instead of just visibility for more accurate lighting,
+   but lose correct blending to surrounding irradiance volumes.
+
+Indirect Light Contribution
+   Capture light bounces from light source.
+
+Emission Contribution
+   Capture emissive surfaces when baking.
+
+
+Clamping
+========
+
+Clamp Direct
+   Clamp incoming direct light. 0.0 disables direct light clamping.
+   Here direct light refers to the light that bounces only once (from the light object)
+   or light coming from emissive materials.
+
+Clamp Indirect
+   Clamp incoming indirect light. 0.0 disables indirect light clamping.
+   Here indirect light refers to the light that bounces off a surface after the first bounce (from the light object)
+   or during the first bounce if the light comes from emissive materials.
+
+.. tip::
+
+   Setting *Clamp Indirect* to a very non-zero value will effectively only record the first light bounce leading.
+
+
+Offset
+======
+
+In order to reduce artifacts caused by bad capture point positioning,
+the bake process adjusts their location before capturing light.
+It moves the capture points slightly away from surrounding surfaces and tries to move them out of objects
+if they are not too far bellow the surface.
+
+Surface Offset
+   Distance to move the capture points away from surfaces.

+Search Distance
+   Distance to search for valid capture positions if the capture point is near the back-face of a single-sided object.

+======

-Next to lighting from the background and any object with an emission shader,

-The difference is that they are not directly visible in the rendered image,
-and can be more easily managed as objects of their own type.

-=====

-Specular
-   Specular Light intensity multiplier. Use it for artistic control. Defines the intensity with which the light object
-   will be visible in reflections on the surface of specular objects, like metals or mirrors.
-   Setting this to 0 will make the light object disappear from specular reflections. Keep it exactly at 1.0 for
-   photo-realistic results.

-   If enabled, uses *Distance* as the custom attenuation distance instead of global Light Threshold.

-
-Shadows
-=======
-
-Common Parameters
------------------
-
-Clip Start
-   Distance from the light object at which the shadow map starts.
-   Any object which is closer to the light than Clip Start will not cast shadows.
-   *Clip Start* is only available for point, spot and area lights.
-
-Bias
-   Bias applied to the depth test to reduce self-shadowing artifacts.
-   This determines, what size of surface details (for example, bumps) will cast shadows on the object itself.
-   If this value is low, small bumps will cast shadows on the object's surface.
-   This might cause jagged shadow edge between the sunny and shadowy side of the object,
-   but it can be smoothed out by turning on :doc:`Soft Shadows </render/eevee/render_settings/shadows>`
-
-
-Contact Shadows
----------------
-
-This type of shadow exists to fix light leaking caused by bias or shadow map undersampling.
-It uses the depth buffer to find occluders (just like Screen Space Reflections).
-However, just like Screen Space Reflections it has the same limitations,
-namely, unknown object thickness and effect disappearing at screen edges.
-
-.. tip::
-
-   The distance of action of Contact Shadows should remain quite small.
-   They are not accurate enough to shadow the entire scene.
-
-Distance
-   World space distance in which to search for screen space occluder.
-
-Bias
-   Bias applied to the ray tracing to reduce self-shadowing artifacts.
-
-Thickness
-   Pixel thickness used to detect occlusion, treating any potential occluder as this thick.
-
-
-.. _eevee-cascaded-shadow-map:
-
-Cascaded Shadow Map
--------------------
-
-Sun lights usually illuminate a large scene with many objects, some close, some far away.
-To optimize shadow calculation in this situation, a technique called Cascaded Shadow Maps is used.
-The distance between the camera's near clip and far clip point is divided into as many equal intervals
-(called cascades) as you set the Count parameter below.
-For each cascade a different resolution shadow will be displayed: higher resolution for closer cascades and lower
-resolution for distant ones.
-Do note that cascade shadow maps are always updated because they depend on the camera position or your view origin in
-the 3D-Viewport. This means they have a high performance impact.
-
-.. note::
-
-   In orthographic view the cascades cover the whole depth range of the camera
-   with an evenly distributed shadow precision.
-
-Count
-   Number of cascades to use. More cascades means better shadow precision but a lower update rate.
-
-Fade
-   When the Fade is greater than 0, the size of each cascade (distance interval) is increased so that neighboring
-   cascades overlap. Then a fade is applied in the overlapping region to provide a smooth transition between cascades.
-   Higher values mean the cascade's size is increased more, which decreases the available shadow resolution
-   inside the cascade since some of it is used in the overlapping region.
-
-Max Distance
-   Distance away from the view origin (or camera origin if in camera view) to cover by the cascades.
-   If the view far clip distance is lower than Max Distance, the view far clip distance will be used.
-   Only works in perspective view.
-
-Distribution
-   Puts more resolution towards the near clip plane. Only works in perspective view.

+      This can be worked around by passing the vertex normals as a custom attribute.
+
+Max Displacement
+   The maximum distance a vertex can be displaced when using true displacement.
+   Displacements over this threshold may cause visibility issues.
+   These visibility issues can be observed when the object is out of view at the edge of screen
+   with parts being displaced inside the view. The object would then disappear because of camera culling.
+   This can also produce missing shadow updates where the displaced geometry is.

+      Also known as forward rendering.
+
+
+Dithered Layers
+---------------
+
+When using *Dithered* render method, the materials are rendered in layers.
+Each layer can only transmit (e.g. refract) light emitted from previous layers.
+If no intersection with the layers below exists, the transmissive BSDFs will fallback to light probes.
+
+Raytraced Transmission
+   Use raytracing to determine transmitted color instead of using only light probes.
+   This prevents the surface from contributing to the lighting of surfaces not using this setting.
+
+
+Sorting Problem
+---------------
+
+When using *Blended* render method, the order in which the color blending happens is important as it

+
+Thickness
+---------
+
+This feature is used to approximate the inner geometry structure of the object without heavy computation.
+This is currently used for Subsurface, Translucent BSDF, Refraction BSDF and the nodes containing them.
+
+If no value is plugged into the output node, a default thickness based on the smallest dimension of the object is computed.
+If a value is connected it will be used as object space thickness (i.e. scaled by object transform).
+A value of zero will disable the thickness approximation and treat the object as having only one interface.
+
+.. note::
+   - The thickness is used to skip the inner part of the object.
+   - Refraction will not refract objects inside the thickness distance.
+   - Shadow casting object will not cast shadow within the thickness distance.
+
+.. tip::
+   - For large or compound meshes (e.g. vegetation), the thickness should be set to the thickness of individual parts (e.g. leaves, grass blades).
+   - Thickness can be baked to textures or custom attributes for more accurate result.
+
+Thickness Mode
+   Determines what model to use to approximate the object geometry.
+
+   :Sphere:
+      Approximate the object as a sphere whose diameter is equal to the thickness defined by the node tree.
+      This is more suited to objects with rounder edges (e.g. a monkey head), and is perfectly suited to spheres.
+
+   :Slab:
+      Approximate the object as an infinite slab of thickness defined by the node tree.
+      This is more suited to very flat or thin objects (e.g. glass panels, grass blades).
+
+From Shadow
+   Use the shadow maps from shadow casting lights to refine the thickness defined by the material node tree.
+   This takes the minimum thickness between the shadow map and the material node tree value.
+   This is useful for objects where pre-computation is difficult (e.g. complex meshes), impossible
+   (e.g. procedural geometry with displacement) or just impractical.
+   However, this will have a performance impact that scale with the number of render samples.
+
+
+.. _bpy.types.Material.volume:
+
+Volume
+======
+
+Intersection
+   Determines which inner part of the mesh will produce volumetric effect.
+
+   :Fast:
+      Each face is considered as a medium interface. Gives correct results for manifold geometry
+      that contains no inner part.
+
+   :Accurate:
+      Faces are considered as medium interface only when they have different consecutive facing.
+      Gives correct results as long as the max ray depth is not exceeded. Has significant memory
+      overhead compared to the fast method.

-Introduction
-************
-
-EEVEE's materials system uses the same node based approach as :doc:`Cycles </render/materials/index>`.
-
-
-Nodes Support
-=============
-
-Due to realtime constraints, not all Cycles features are available in EEVEE.
-See :doc:`/render/eevee/materials/nodes_support`.
-
-
-Performance
-===========
-
-Performance is highly dependent on the number of BSDF nodes present in the node tree.
-
-.. tip::
-
-   Prefer using the Principled BSDF instead of multiple BSDF nodes because EEVEE is optimized for it.

-================

-Backface Culling hides the back side of faces.
-
-
-.. _bpy.types.Material.blend_method:
-
-Blend Mode
-==========
-
-After calculating the color of a surface, the blend mode defines how it is added to the color buffer.
-Depending on this, the final color will be different.
-
-.. note::
-
-   Alpha Blending is considered a "Transparent" blend mode
-   and has implications regarding screen space effects.
-
-Opaque
-   The previous color will be overwritten by the surface color.
-   The alpha component is ignored. This is the fastest option.
-
-Alpha Clip
-   The previous color will be overwritten by the surface color,
-   but only if the alpha value is above the *Clip Threshold* value.
-
-Alpha Hashed
-   The previous color will be overwritten by the surface color,
-   but only if the alpha value is above a random clip threshold.
-   This statistical approach is noisy but is able to approximate alpha blending without any sorting problem.
-   Increasing the sample count in the render settings will reduce the resulting noise.
-
-Alpha Blending
-   Use alpha blending to overlay the surface color on top of the previous color.
-
-
-Sorting Problem
----------------
-
-When writing to the color buffer using transparent blend modes,
-the order in which the color blending happens is important as it can change the final output color.
-As of now EEVEE does not support per-fragment (pixel) sorting or per-triangle sorting.
-Only per-object sorting is available and is automatically done on all transparent surfaces based on object origin.
-
-.. note::
-
-   Per-object sorting has a performance cost and having thousands of
-   these objects in a scene will greatly degrade performance.
-
-.. _bpy.types.Material.show_transparent_back:
-
-Show Backface
-   If enabled, all transparent fragments will be rendered.
-   If disabled, only the front-most surface fragments will be rendered.
-   Disable this option to ensure correct appearance of transparency from any point of view.
-   When using *Alpha Blending* this option should be disabled because with *Alpha Blending*,
-   the order in which triangles are sorted is important.
-
-
-.. _bpy.types.Material.shadow_method:
-
-Shadow Mode
-===========
-
-Type of shadows used for a transparent surface.
-EEVEE does not support colored shadow maps.
-
-Half transparent shadows can be produced by using hashed transparent shadows and
-a larger Soft value on the shadow map.
-
-.. note::
-
-   This option does not change the behavior of contact shadows which are traced using the depth buffer.
-   If the material is writing to the depth buffer
-   (in other words, if the blend mode is set to either *Opaque*, *Alpha Clip* or *Alpha Hashed*),
-   contact shadows will be cast by the surface material regardless of the *Transparent Shadow* type.
-
-None
-   The surface will not cast any shadow.
-
-Opaque
-   The surface will cast shadows like an opaque surface.
-
-Alpha Clip
-   The surface will cast shadows like an opaque surface,
-   but only areas where the alpha value is above the *Clip Threshold* value.
-
-Alpha Hashed
-   The surface will cast shadows like an opaque surface,
-   but only areas where the alpha value is above a random threshold.

-
-Clip Threshold
-==============
-
-Threshold value for Alpha Clip mode in *Blend Mode* and *Shadow Mode*.
-
-
-Screen Space Refraction
-=======================
-
-Enabling Screen Space Refraction on a surface means that refraction BSDFs
-will do a ray trace against the depth buffer to find the most accurate refracted color.
-This has a big performance cost if the surface covers a lot of pixels.
-
-Screen Space Reflections and Ambient Occlusion are not compatible with Screen Space Refraction.
-They will be disabled on the surfaces that use it.
-Surfaces that use Screen Space Refraction will not appear in Screen Space Reflections at the right place.
-Surfaces that use Screen Space Refraction will not cast Ambient Occlusion onto other surfaces.
-
-If this option is disabled or if the Screen Space Refraction ray tracing fails,
-the refracted ray will use the color of the nearest probe.
-
-.. _bpy.types.Material.use_screen_refraction:
-
-Screen Space Refraction
-   Enables screen space refraction.
-
-.. _bpy.types.Material.refraction_depth:
-
-Refraction Depth
-   If Refraction Depth is not 0.0, all refraction BSDFs in the shader will act as if
-   the object is a thin slab of the refraction material having this thickness.
-   This will model a second refraction event that will double the absorption color and
-   start the refraction ray after this second event.
-
-   This option greatly increases the quality of thin glass objects.
-
-
-.. _bpy.types.Material.use_sss_translucency:
-
-Subsurface Translucency
-=======================
-
-EEVEE's Subsurface Scattering algorithm works by blurring the irradiance in screen space.
-This means that if no visible part of the surface is lit, the effect disappears.
-
-However, true Subsurface Scattering goes beneath the surface and can travel a large distance.
-This is why a human ear lit from behind appears red on the front side.
-
-That is what this effect mimics. This translucency approximation only works
-with lights that have shadow maps and only on Subsurface BSDFs (not the Translucency BSDFs).
-It does not work with indirect lighting. The soft parameter of the shadow maps also affects this effect.
-
-
-Pass Index
-==========
-
-Index number for the *Material Index* :doc:`render pass </render/layers/passes>`.
-This can be used to give a mask to a material which then can be read with
-the :doc:`ID Mask Node </compositing/types/mask/id_mask>` in the Compositor.

-
-   :doc:`Volume Objects </modeling/volumes/introduction>` are not supported.

-Shadows
-*******
-
-These settings influence shadows which appear on objects because there is another object (the occluder)
-between them and a Light. EEVEE uses a technique called Shadow Mapping to calculate these shadows.
-A shadow map is calculated by looking around from the position of each Light and finding the objects
-which are closest to the Light. These objects are called the nearest occluders.
-Everything which is behind (or, you can say, covered by) the nearest occluders will be in shadow.
-
-The shadow map is a cube (hence the term "cubemap") and the Light is in the middle of this cube.
-The cube has six sides and each side is divided into a grid.
-You can set the resolution of the grid (for example, 512 × 512 pixels) with the *Cube Size* setting below.
-During shadow calculation, the nearest occluders are only searched at grid points but not between grid points.
-Because of this, the edge of the calculated shadow will appear pixelated at low Cube Size settings.

-   If you want to make the edge of shadows less pixelated, then increase this value.

-Cascade Size

-
-High Bitdepth
-   This option can help reduce some artifacts due to float imprecision inside the shadow maps.

-Soft Shadows

-
-Light Threshold
-   The minimum amount of light for a light to contribute for lighting.
-   This light threshold does not take the light shape into account and may not suit every case.
-   That is why Blender provides a :ref:`per-light override <bpy.types.Light.cutoff_distance>`
