[12.0.0] - 2021-01-11

Added

Added support for default sprite mask shaders for the 2D Renderer in URP.
Added View Vector node to mimic old behavior of View Direction node in URP.
Added support for the PlayStation 5 platform.
Enabled deferred renderer in UI.
Added support for light layers, which uses Rendering Layer Masks to make Lights in your Scene only light up specific Meshes.
2D Light Texture Node. A Shader Graph node that enable sampling of the Light Textures generated by the 2D Renderer in a lit scene.
Fixed an error where multisampled texture being bound to a non-multisampled sampler in XR. case 1297013
Added _SURFACE_TYPE_TRANSPARENT keyword to URP shaders.
Added Depth and DepthNormals passes to particles shaders.
Added support for SSAO in Particle and Unlit shaders.
Added Decal support. This includes new Decal Projector component, Decal renderer feature and Decal shader graph.
Added a SpeedTree 8 Shader Graph but did not set it as the default when importing or upgrading Speed Tree 8 assets. Because URP doesn't yet support per-material culling, this Shader Graph does not yet behave in the same way as the existing handwritten SpeedTree 8 shader for URP.
Added optional Depth Priming. Allows the forward opaque pass of the base camera to skip shading certain fragments if they don't contribute to the final opaque output.
Added blending and box projection for reflection probes.
Added 'Store Actions' option that enables bandwidth optimizations on mobile GPU architectures.
Added "Allow Material Override" option to Lit and Unlit ShaderGraph targets. When checked, allows Material to control the surface options (transparent/opaque, blend mode, etc).
Added a new UI for Render Pipeline Converters. Used now for Built-in to Universal conversion.
Added sections on Light Inspector.
Reorder camera inspector to be in the same order as HDRP.
Added new URP Debug Views under Window/Analysis/Rendering Debugger.
Added support for controlling Volume Framework Update Frequency in UI on Cameras and URP Asset as well as through scripting.
Added URP Global Settings Asset to the Graphics Settings - a common place for project-wide URP settings.
Added possibility to rename light layer values.
Added Light cookies support to directional, point and spot light. Directional light cookie is main light only feature.
Added GetUniversalAdditionalLightData, a method that returns the additional data component for a given light or create one if it doesn't exist yet.
VFX: Basic support of Lit output.
Added Motion Vector render pass for URP.
VFX: Fix light cookies integration.
Added Lights 2D to the Light Explorer window.
Two new URP specific scene templates, Basic which has a camera and directional light, then Standard which has the addition of a global volume with basic post effects setup.
Added Render Settings Converter to the Render Pipeline Converter, this tool creates and assigns URP Assets based off rendering settings of a Builtin project.
XR: Added Late Latching support to reduce VR latency (Quest).
Fixed incorrect shadow fade in deferred rendering mode.
Added a help button on material editor to show the shader documentation page
URP global setting for stripping post processing shader variants.
URP global setting for stripping off shader variants.

Changed

Moved fog evaluation from vertex shader to pixel shader. This improves rendering of fog for big triangles and fog quality. This can change the look of the fog slightly.
UNITY_Z_0_FAR_FROM_CLIPSPACE now remaps to [0, far] range on all platforms consistently. Previously OpenGL platforms did not remap, discarding small amount of range [-near, 0].
Moved all 2D APIs out of experimental namespace.
ClearFlag.Depth does not implicitely clear stencil anymore. ClearFlag.Stencil added.
The Forward Renderer asset is renamed to the Universal Renderer asset. The Universal Renderer asset contains the property Rendering Path that lets you select the Forward or the Deferred Rendering Path.
Improved PixelPerfectCamera UI/UX
Changed Pixel Snapping and Upscale Render Texture in the PixelPerfectCamera to a dropdown.
Move Assets/Create/Rendering/Universal Render Pipeline/Pipeline Asset (2D Renderer) to Assets/Create/Rendering/URP Asset (with 2D Renderer)
Move Assets/Create/Rendering/Universal Render Pipeline/2D Renderer to Assets/Create/Rendering/URP 2D Renderer
Move Assets/Create/Rendering/Universal Render Pipeline/Renderer Feature to Assets/Create/Rendering/URP Renderer Feature
Move Assets/Create/Rendering/Universal Render Pipeline/Post-process Data to Assets/Create/Rendering/URP Post-process Data
Move Assets/Create/Rendering/Universal Render Pipeline/Pipeline Asset (Forward Renderer) to Assets/Create/Rendering/URP Asset (with Forward Renderer)
Move Assets/Create/Rendering/Universal Render Pipeline/XR System Data to Assets/Create/Rendering/URP XR System Data
Move Assets/Create/Rendering/Universal Render Pipeline/Forward Renderer to Assets/Create/Rendering/URP Forward Renderer
Removing unused temporary depth buffers for Depth of Field and Panini Projection.
Optimized the Bokeh Depth of Field shader on mobile by using half precision floats.
Changed UniversalRenderPipelineCameraEditor to URPCameraEditor
Made 2D shadow casting more efficient
Reduced the size of the fragment input struct of the TerrainLitPasses and LitGBufferPass, SimpleLitForwardPass and SimpleLitGBufferPass lighting shaders.
Bokeh Depth of Field performance improvement: moved some calculations from GPU to CPU.
Advanced Options > Priority has been renamed to Sorting Priority
Opacity as Density blending feature for Terrain Lit Shader is now disabled when the Terrain has more than four Terrain Layers. This is now similar to the Height-blend feature for the Terrain Lit Shader.
DepthNormals passes now sample normal maps if used on the material, otherwise output the geometry normal.
SSAO Texture is now R8 instead of ARGB32 if supported by the platform.
Enabled subsurface scattering with GI on handwritten Universal ST8 shader.
Material upgrader now also upgrades AnimationClips in the project that have curves bound to renamed material properties.
2D Lights now inherit from Light2DBase.
The behavior of setting a camera's Background Type to "Dont Care" has changed on mobile. Previously, "Dont Care" would behave identically to "Solid Color" on mobile. Now, "Dont Care" corresponds to the render target being filled with arbitrary data at the beginning of the frame, which may be faster in some situations. Note that there are no guarantees for the exact content of the render target, so projects should use "Dont care" only if they are guaranteed to render to, or otherwise write every pixel every frame.
Stripping shader variants per renderer features instead of combined renderer features.
When MSAA is enabled and a depth texture is required, the opaque pass depth will be copied instead of scheduling a depth prepass.
URP Asset Inspector - Advanced settings have been reordered under Show Additional Properties on each section.
Changed the default name when a new urp asset is created.
URP Asset Inspector - General section has been renamed to Rendering.
Refactored some of the array resizing code around decal projector rendering to use new APIs in render core
UniversalRendererData and ForwardRendererData GUIDs have been reversed so that users coming from 2019LTS, 2020LTS and 2021.1 have a smooth upgrade path, you may encounter issues coming from 2021.2 Alpha/Beta versions and are recommended to start with a fresh library if initial upgrade fails.
VFX: New shadergraph support directly on Universal target.
URP will no longer render via an intermediate texture unless actively required by a Renderer Feature. See the upgrade guide for compatibility options and how assets are upgraded.

[7.1.1] - 2019-09-05

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 an option that disables the depth/stencil buffer for the 2D Renderer.
Added manipulation handles for the inner cone angle for spot lights.
Added documentation for the built-in post-processing solution and Volumes framework (and removed incorrect mention of the PPv2 package).

Changed

Increased visible lights limit for the forward renderer. It now supports 256 visible lights except in mobile platforms. Mobile platforms support 32 visible lights.
Increased per-object lights limit for the forward renderer. It now supports 8 per-object lights in all platforms except GLES2. GLES2 supports 4 per-object lights.
The Sprite-Lit-Default shader and the Sprite Lit Shader Graph shaders now use the vertex tangents for tangent space calculations.
Temporary render textures for cameras rendering to render textures now use the same format and multisampling configuration as camera's target texture.
All platforms now use R11G11B10_UFloat format for HDR render textures if supported.
There is now a list of ScriptableRendererData on the Render Pipeline Asset as opposed to a renderer type. These are available to all Cameras and are included in builds.
The renderer override on the Camera is now an enum that maps to the list of ScriptableRendererData on the Render Pipeline Asset.
Pixel Perfect Camera now allows rendering to a render texture.
Light2D GameObjects that you've created now have a default position with z equal to 0.

[6.5.0] - 2019-03-07

Added

You can now create a custom forward renderer by clicking on Assets/Create/Rendering/Lightweight Render Pipeline/Forward Renderer. This creates an Asset in your Project. You can add additional features to it and drag-n-drop the renderer to either the pipeline Asset or to a camera.
You can now add ScriptableRendererFeature to the ScriptableRenderer to extend it with custom effects. A feature is an ScriptableObject that can be drag-n-dropped in the renderer and adds one or more ScriptableRenderPass to the renderer.
ScriptableRenderer now exposes interface to configure lights. To do so, implement SetupLights when you create a new renderer.
ScriptableRenderer now exposes interface to configure culling. To do so, implement SetupCullingParameters when you create a new renderer.
ScriptableRendererData contains rendering resources for ScriptableRenderer. A renderer can be overridden globally for all cameras or on a per-camera basis.
ScriptableRenderPass now has a RenderPassEvents. This controls where in the pipeline the render pass is added.
ScriptableRenderPass now exposes ConfigureTarget and ConfigureClear. This allows the renderer to automatically figure out the currently active rendering targets.
ScriptableRenderPass now exposes Blit. This performs a blit and sets the active render target in the renderer.
ScriptableRenderPass now exposes RenderPostProcessing. This renders post-processing and sets the active render target in the renderer.
ScriptableRenderPass now exposes CreateDrawingSettings as a helper for render passes that need to call ScriptableRenderContext.DrawRenderers.

Changed

Removed RegisterShaderPassName from ScriptableRenderPass. Instead, CreateDrawingSettings now takes one or a list of ShaderTagId.
Removed remaining experimental namespace from LWRP. All APIrelated to ScriptableRenderer, ScriptableRenderPass, and render pass injection is now out of preview.
Removed SetRenderTarget from ScriptableRenderPass. You should never call it. Instead, call ConfigureTarget, and the renderer automatically sets up targets for you.
Removed RenderFullscreenQuad from ScriptableRenderer. Use CommandBuffer.DrawMesh and RenderingUtils.fullscreenMesh instead.
Removed RenderPostProcess from ScriptableRenderer. Use ScriptableRenderPass.RenderPostProcessing instead.
Removed postProcessingContext property from ScriptableRenderer. This is now exposed in RenderingUtils.postProcessingContext.
Removed GetCameraClearFlag from ScriptableRenderer.

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.
