- 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.
- Added the possibility to add an override transform on the camera for volume interpolation
- Added desired lux intensity and auto multiplier for HDRI sky
- Added an option to disable light by type in the debug menu
- Added gradient sky
- Split EmissiveColor and bakeDiffuseLighting in forward avoiding the emissiveColor to be affect by SSAO
### Fixed
- Fixed an issue with PreIntegratedFGD texture being sometimes destroyed and not regenerated causing rendering to break
- Refactored Constant Buffers to avoid hitting the maximum number of bound CBs in some cases.
- Fixed the light range affecting the transform scale when changed.
- Snap to grid now works for Decal projector resizing.
- Added a warning for 128x128 cookie texture without mipmaps
### Changed
- Movde Render Pipeline Debug "Windows from Windows->General-> Render Pipeline debug windows" to "Windows from Windows->Analysis-> Render Pipeline debug windows"
- 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.
- Refactor shader code: Rename GetBakedDiffuseLighting to ModifyBakedDiffuseLighting. This function now handle lighting model for transmission too. Lux meter debug mode is factor outisde.
- Refactor shader code: GetBakedDiffuseLighting is not call anymore in GBuffer or forward pass, including the ConvertSurfaceDataToBSDFData and GetPreLightData, this is done in ModifyBakedDiffuseLighting now
- Refactor shader code: Added a backBakeDiffuseLighting to BuiltinData to handle lighting for transmission
- Refactor shader code: Material must now call InitBuiltinData (Init all to zero + init bakeDiffuseLighting and backBakeDiffuseLighting ) and PostInitBuiltinData
### 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.

// This matrix needs to be updated at the draw call frequency.
- If the current render pipeline is not compatible, master nodes now display an error badge.
- The preview shader now only considers the current render pipeline. Because of this there is less code to compile, and therefore the preview shader will compile faster.
- When you rename a shader graph or sub shader graph locally on your disk, the title of the Shader Graph window, black board, and preview also updates.
- Removed legacy matrices from Transfomation Matrix node.
- The Lightweight PBR subshader now normalizes normal, tangent, and view direction correctly.
- Texture 2D Array and Texture 3D nodes can no longer be used in the vertex shader.
- Shader graphs using alpha clip now generate correct depth and shadow passes.
