[7.2.0] - 2020-02-10

Added

Camera Stacking in URP

Added support for Camera Stacking when using the Forward Renderer. This introduces the Camera Render Type property. A Base Camera can be initialized with either the Skybox or Solid Color, and can combine its output with that of one or more Overlay Cameras. An Overlay Camera is always initialized with the contents of the previous Camera that rendered in the Camera Stack.
Added XR multipass rendering. Multipass rendering is a requirement on many VR platforms and allows graceful fallback when single-pass rendering isn't available.
Added support for Post Processing Version 2 (PPv2) as a fallback post-processing solution, in addition to URP's integrated post-processing solution. This enables developers to use PPv2 with Unity 2019 LTS.
Added Transparency Sort Mode, Transparency Sort Axis, and support for a user defined default material to 2DRendererData.
Added the option to toggle shadow receiving on transparent objects.
Added support for particle shaders to receive shadows.
Added AssetPostprocessors and Shadergraphs to handle Arnold Standard Surface and 3DsMax Physical material import from FBX. Basic PBR material properties like Base Color, Metalness, Roughness, Specular IOR, Emission and Normals are imported and mapped to custom shaders in Unity.

Changed

Removed final blit pass to force alpha to 1.0 on mobile platforms.
Blend Styles in the 2DRendererData are now automatically enabled/disabled.
When using the 2D Renderer, Sprites render with a faster rendering path when no lights are present.

Upgrade Guide

The render pipeline now handles custom renderers differently. You must now set up renderers for the Camera on the Render Pipeline Asset.
Render Pipeline Assets upgrades automatically and either creates a default forward renderer in your project or links the existing custom one that you've assigned.
If you have custom renderers assigned to Cameras, you must now add them to the current Render Pipeline Asset. Then you can select which renderer to use on the Camera.

Added

Added shader function GetMainLightShadowParams. This returns a half4 for the main light that packs shadow strength in x component and shadow soft property in y component.
Added shader function GetAdditionalLightShadowParams. This returns a half4 for an additional light that packs shadow strength in x component and shadow soft property in y component.
Added a Debug Level option to the Render Pipeline Asset. With this, you can control the amount of debug information generated by the render pipeline.
Added ability to set the ScriptableRenderer that the Camera renders with via C# using UniversalAdditionalCameraData.SetRenderer(int index). This maps to the Renderer List on the Render Pipeline Asset.
Added shadow support for the 2D Renderer.
Added ShadowCaster2D, and CompositeShadowCaster2D components.
Added shadow intensity and shadow volume intensity properties to Light2D.

Dynamic Batching can be enabled in the pipeline asset
Pipeline now strips unused or invalid variants and passes based on selected pipeline capabilities in the asset. This reduces build and memory consuption on target.
Shader stripping settings were added to pipeline asset

Changed

Pipeline

Pipeline code is now more modular and extensible. A ForwardRenderer class is initialized by the pipeline with RenderingData and it's responsible for enqueueing and executing passes. In the future pluggable renderers will be supported.
On mobile 1 directional light + up to 4 local lights (point or spot) are computed
On other platforms 1 directional light + up to 8 local lights are computed
Multiple shadow casting lights are supported. Currently only 1 directional + 4 spots light shadows. #### Shading Framework
Directional Lights are always considered a main light in shader. They have a fast shading path with no branching and no indexing.
GetMainLight() is provided in shader to initialize Light struct with main light shading data.
Directional lights have a dedicated shadowmap for performance reasons. Shadow coord always comes from interpolator.
MainLigthRealtimeShadowAttenuation(float4 shadowCoord) is provided to compute main light realtime shadows.
Spot and Point lights are always shaded in the light loop. Branching on uniform and indexing happens when shading them.
GetLight(half index, float3 positionWS) is provided in shader to initialize Light struct for spot and point lights.
Spot light shadows are baked into a single shadow atlas.
Shadow coord for spot lights is always computed on fragment.
Use LocalLightShadowAttenuation(int lightIndex, float3 positionWS) to comppute realtime shadows for spot lights.
