 Screen Space Effects
 ====================
 
-EEVEE is not a path tracing engine and cannot do ray-triangle intersection.
+Ray-triangle intersection is not currently supported.
 Instead of this, EEVEE uses the depth buffer as an approximated scene representation.
 This reduces the complexity of scene scale effects and enables a higher performance.
 However, only what is in inside the view can be considered when computing these effects.

-Ambient Occlusion
------------------

-- Objects are treated as infinitely thick, producing overshadowing if the *Distance* is really large.
-- Objects are treated as uniformly thick, producing over- or under-shadowing depending on the

 Raytracing
 ----------
 
-- Screen Space Reflections will reflect transparent objects and objects using Screen Space Refraction
+- Blended materials and materials using raytrace refractions will not appear in dithered materials reflections.
-  but without accurate positioning due to the one layer depth buffer.
+- Blended materials are not compatible with raytracing.
-- Blended materials and materials using raytrace refractions will not appear in dithered materials.
-- Blender materials are not compatible with raytracing.
 - Only one refraction event is correctly modeled.
+  An approximation of the second refraction event can be approximated using the :ref:`eevee-thickness-workflow`.
 - Only dithered materials *not* using Raytrace Refractions can be refracted.

-Subsurface Scattering
----------------------
-
-- Only one BSSRDF can produce screen space subsurface scattering.
-- The evaluated BSSRDF is currently arbitrarily chosen.
-- A maximum of 254 different surfaces can use subsurface scattering.
-- Only scaling is adjustable per pixel. Individual RGB radii are adjustable in the socket default value.
-- Input radiance from each surfaces are not isolated during the blurring,
-  leading to light leaking from surface to surface.

-Refractions
-   Refraction is faked by sampling the same reflection probe used by the Glossy BSDFs,
-   but using the refracted view direction instead of the reflected view direction.
-   Only the first refraction event is modeled correctly.
-   An approximation of the second refraction event can be used for relatively thin objects using Refraction Depth.
-   Using Screen Space refraction will refract what is visible inside the view,
-   and use the nearest probe if there is no hit.
-
-   Surfaces that use raytrace refraction will not cast ambient occlusion onto other materials not
-   using this option.

 Shader Nodes
 ============
 
 - All BSDF's are using approximations to achieve realtime performance
   so there will always be small differences between Cycles and EEVEE.
 - Some utility nodes are not yet compatible with EEVEE.
+- Certain combinations of BSDF's will result in more noise than others. This is the case of mixing Diffuse BSDF and Refraction BSDF.
