 - Decal now support per channel selection mask. There is now two mode. One with BaseColor, Normal and Smoothness and another one more expensive with BaseColor, Normal, Smoothness, Metal and AO. Control is on HDRP Asset. This may require to launch an update script for old scene: 'Edit/Render Pipeline/Single step upgrade script/Upgrade all DecalMaterial MaskBlendMode'.
 - Decal now supports depth bias for decal mesh, to prevent z-fighting
 - Decal material now supports draw order for decal projectors 
+- Added LightLayers support (Base on mask from renderers name RenderingLayers and mask from light name LightLayers - if they match, the light apply) - cost an extra GBuffer in deferred (more bandwidth)
+- When LightLayers is enabled, the AmbientOclusion is store in the GBuffer in deferred path allowing to avoid double occlusion with SSAO. In forward the double occlusion is now always avoided.

 ### Fixed
 - Fixed an issue with PreIntegratedFGD texture being sometimes destroyed and not regenerated causing rendering to break
 - Update detail map formula for smoothness and albedo, goal it to bright and dark perceptually and scale factor is use to control gradient speed
 - Refactor the Upgrade material system. Now a material can be update from older version at any time. Call Edit/Render Pipeline/Upgrade all Materials to newer version
 - Change name EnableDBuffer to EnableDecals at several place (shader, hdrp asset...), this require a call to Edit/Render Pipeline/Upgrade all Materials to newer version to have up to date material.
+- Refactor shader code: BakeLightingData structure have been replace by BuiltinData. Lot of shader code have been remove/change.
+- Refactor shader code: All GBuffer are now handled by the deferred material. Mean ShadowMask and LightLayers are control by lit material in lit.hlsl and not outside anymore. Lot of shader code have been remove/change.

 ### Added
 - Added support for RendererPriority on Renderer. This allow to control order of transparent rendering manually. HDRP have now two stage of sorting for transparent in addition to bact to front. Material have a priority then Renderer have a priority.
