 ### Added
 - Added subshadergraphs for SpeedTree 8 shadergraph support: SpeedTree8Wind, SpeedTree8ColorAlpha, SpeedTree8Billboard.

+- Added View Vector Node doc
 
 ### Changed
 - Only ShaderGraph keywords count towards the shader permutation variant limit, SubGraph keywords do not.
 
 ### Fixed
+- Updated/corrected View Direction doc
 - Fixed an issue where horizontal scrollbars in graph sub windows could not have their lower scroll button used due to being overlapped by the resize handles [1320993]
 - Fixed an issue where nodes with ports on one side would appear incorrectly on creation [1262050]
 - Fixed a broken link in the TOC to Main Preview

 ## Description
 
-Provides access to the mesh vertex or fragment's **View Direction** vector. This is the vector from the vertex or fragment to the camera. The coordinate space of the output value can be selected with the **Space** dropdown parameter.
+Provides access to the mesh vertex or fragment's **View Direction** vector. This is the vector from the vertex or fragment to the camera. Select a **Space** to modify the coordinate space of the output value.
+In versions prior to version 11.0, the **View Direction Node** works differently in HDRP than in URP. In URP, it only stored Object space vectors normalized. HDRP stores all vectors normalized.
+
+From 11.0 onwards, this node stores all vectors normalized in both the **High-Definition Render Pipeline** and the **Universal Render Pipeline**.
+
+If you want to keep using the old behavior in URP outside of object space, replace this node with a **View Vector Node**.
