-Below you can see a comparison table showing the full feature set of each edition. The Lite edition has an add-on sold separately which adds LWRP support in Unity 2019.1+ (this add-on is included free of charge in the Standard / Team edition). To learn more about the specific limits and differences between the standard Unity rendering pipeline (also known as Built-in) and the new LWRP pipeline, please go to the corresponding section of the documentation.

-Different packages are provided to support the different URP and HDRP releases. These packages are clearly labeled with the pipeline's name and version so they are easy to install, just by unpacking their contents inside the Unity Editor after double clicking on either one.

 To achieve the best results and especially if you plan to use the advanced Water Shaders with URP, you must change the settings of the Scriptable Render Pipeline Asset that you are using (you can find it in Project Settings / Graphics) and enable the Opaque and Depth texture rendering features. This will ensure that all the internal data required by PIDI Planar Reflections 3 is generated.

-While we do our best to keep up to date with LWRP releases there may be times when Unity updates their pipelines and adds or removes functionality from them (and in most cases breaking the compatibility of LWRP shaders) before we can issue the corresponding update. If your version of LWRP does not load the shaders appropriately or the demo scenes inside the URP Add on folder show pink materials please be patient, as we will issue the corresponding patch usually within 1-2 days of a new LWRP release or contact us to let us know the details of the error to our [[support@irreverent-software.com|support email]].

-In some cases you may want to simulate more accurate PBR reflections by using depth-based blur on them (which makes the objects blurrier the further away they are from a surface) or use the depth features of the reflection to generate an accurate mask that allows you to mix real-time and static (or baked) cubemap based reflections.

+==== Blurred Reflections Pass ====
+<WRAP justify>
+Starting with version 3.5, PIDI Planar Reflections 3 includes a new feature called "Blur Pass". This feature allows you to apply a high quality Gaussian Blur filter to the reflections rendered by the asset right before assigning them to the material. This blur pass is applied by the caster on a per-object and per-material basis.
+</WRAP>
+\\
+{{ :planar3_reflectionsblur.jpg |}}
+\\
+<WRAP justify>
+There are two ways of applying this blur pass, either to the Final Result of the reflection rendering process or as a separate pass to be stored in a new texture2D parameter called "_BlurReflectionTex". Using the Final Result mode will work with any shader compatible with our reflection system while the Separate Pass mode requires additional work to implement the new _BlurReflectionTex parameter and how its contents will be used. All the included PBR shaders in all rendering pipelines implement and work best with a Separate Blur Pass.
