[ Update guide ]

2.4.0

Fixed:

- Shader error when building on MacOS due to VR-specific code being activated

- (Unity 2023.2+) Possible build error, causing a black screen, when effects are used but no post-processing is.

2.3.9

Fixed:

- Sunshafts fading out when sun light was directed straight down and camera faced upwards

2.3.8

Changed:

- An error is now displayed in the UI if Render Graph is enabled in Unity 6+, with the option to disable it.

- LUT extractor no longer automatically executes when the input file was changed (related to bug fix below)

Fixed:

- Issue with installation causing all textures in the project to reimport (Unity bug introduced in 2020.2)

- (URP) False-positive warning in the effect UI regarding the use of the 2D Renderer.

- Shader compile error on PS5 when using the Fog shading function in an external shader.

- Truncation warning in Refraction shader.

- Visible aliasing in Caustics effect.

2.3.7

Fixed:

- Script compile errors when using the Built-in RP but the "Core RP Library" package was also installed.

2.3.6

Added:

- (URP) Support for switching between a 3D and 2D renderer, or switching rendering paths

Fixed:

- Effects appearing as a gray screen in Unity 2022.2+ when using the 2D renderer or having the "Skip Transparents" option enabled on a render feature.

- Sketch, canceling out Bloom or other HDR-based effects.

- Fog, if Directional Light shading was disabled, a darker tint was present when the sun would be in the sky

2.3.5

Added:

- Color Split, "Luminance threshold" parameter, making it possible to limit the effect to emissive surfaces.

- Transition, color parameter (default was black) and invert option.

- Refraction, color tint parameter.

- Fog, directional light exponent parameter

- Fog, now supports height fading into the skybox

Changed:

- Refraction, re-authored all sample textures for improved quality.

- Reduced number of texture samplers in Fog shader library, to avoid reaching the maximum of 16 samplers when incorporated into a surface shader.

- Color Split, "Edge Masking" parameter now scales down the offset, rather than decreasing the opacity.

- (URP) Fog shading function (for transparent materials) is now tied to a boolean. If the volume component isn't present the fog shading will be skipped.

- (URP) Edge Detection now uses the GBuffer information when deferred rendering is used

Fixed:

- (URP) Shader errors in Unity 2023.2+ due to now clashing parameter names

- (URP) Effects causing scene to be flooded with shadows when using Deferred rendering in Unity 2022.2+

2.3.4

Added

- (URP) Render features now have the option to render before/after Unity's built in post processing effects (3D renderer only).

Fixed:

- An effect's shader not being included in a build if a volume component was added during play mode. (a build preprocessor script now ensures this)

- (URP) Edge Detection effect "Normals sensitivity" parameter not having any effect for orthographic camera's

- Fog, skybox influence parameter incorrectly affecting transparent materials that incorporate the Fog.hlsl shader library.

Changed:

- A warning is now displayed below texture parameters if they are not overridden. Would otherwise cause them to default to a black texture in a build due to bug related to volume blending logic.

2.3.3

Added:

- Pixelize, option to center pixels and maintain a square aspect ratio

Fixed:

- (URP) Effect rendering as gray when editor is paused (applies to effects with the 'Skip Transparents' option enabled and VR usage).

- Fog, skybox color mode, not working correctly with skybox shaders that use UV coordinates.

- GetFogDensity sub-graph throwing an error about an uninitialized variable.

2.3.2

Added:

- (Built-in RP) Support for Fog integration into custom transparent shaders (see updated documentation).

Changed:

- (URP) Optimized early-out behaviour for effects. No resources are allocated if any effect shouldn't render.

- (Built-in RP) Fog now executes before transparent materials render by default.

Fixed:

- If the asset was installed through the Package Manager, installer failed to detect URP as installed.

- (URP) Black screen in a build if a render feature was added, yet no matching volume component was present on any profiles in the project.

- (URP) Fixes for Shader Graph nodes, these now also use the same shader functions under the hood as the included effects do.

- (URP) Shader Graph, shader errors when using the "ApplyFog" sub-graph in combination with a "Tiling And Offset" node

2.3.1

Changed:

- Fog, distance density parameter is now unclamped in the inspector.

- Tilt Shift effect no longer requires an intermediate render pass.

Fixed:

- (Built-in RP) Shader compile error about "Luminance" function redefinition when using the Metal or Vulkan graphics API

- (URP) Tilt Shift no longer appearing to have an effect since last update (when HDR is enabled).

- Script compile error when both the Universal RP and Post Processing packages were installed, preventing a proper installation error from being displayed.

- Fog turning black if the skybox shader in use was not double-sided.

2.3.0

Minimum supported version is now Unity 2020.3, and URP 10.3.2.

Shaders are no longer in "Resources" folders, meaning only effects present on volume profiles will be included in a build.

- The installer that pops up when updating will automatically move them for you.

Added:

- Single Pass Instanced VR rendering compatibility for: (Built-in RP requires Unity 2021.2+ for a bug fix)

* Edge Detection effect

* Sun Shafts

* (Built-in RP) Distance fading functionality on effects

- Pixelize, popular retro resolution presets. As well as a custom resolution height.

Changed:

- (Built-in RP) Shaders now use the default UnityCG shader libraries. This ensures compatibility moving forward with core Unity changes.

* The Fog.hlsl shader library can now be properly integrated into other shaders.

- (URP) Updated framework to use the new RTHandles API. Though mainly to silence any obsolete API warnings.

- (URP) Effects are now listed in the Frame Debugger using a better readable name.

- Fog, no longer relies on a hidden camera to capture the skybox color. This removes any overhead related to camera processing (in URP this was already the case).

- Minor shader optimization for any effect using a blur.

- Minor shader optimization for the Edge Detection effect.

- Color Split effect now has an "Edge Masking" parameter.

- Sunshafts, renamed resolution dropdown values to "Full/Half/Third/Quarter" (the last being a new addition).

Fixed:

- (URP) Pre-emptive fixes for Unity 2022.2 & 2023.1.

- Blur (Gaussian mode) causing a slight discoloration.

- (Built-in RP) Blur effect not rendering properly when using Single Pass Instanced VR rendering.

- Texture parameters being blank in a build, unless overridden (they're now overridden automatically when first adding an effect)

- Caustics effect appearing too bright when using the Gamma color space and HDR

- (Built-in RP) Color Split effect causing FXAA to stop taking effect.

- (URP) Resolved any unintentional GC allocations.

- (URP 13+) Sunshafts, warning about "temporary render texture" being thrown at the start of each frame

Removed:

- Retired support for Single Pass Stereo VR rendering since it's been deprecated after Unity 2019.

- Unnecessary Blit from Blur and Sun Shafts effects.

2.2.0

Added:

- Contrast Adaptive sharpening method to Sharpen effect

- Color Grading LUT, vibrancy filter

- Radial Blur, now has a center and angle parameter, allowing for a swirl-like blur

- Kaleidoscope, parameter to set the pivot point, horizontal/vertical splits and to maintain the screen's aspect ratio

- (URP) Render features now have a dropdown to select allowed camera types (defaults to Game & Scene view)

- (URP) Added option to Edge Detection render feature to execute before transparent materials are rendered

Changed:

- Backported depth to world reconstruction method from URP. This affects: Fog, Cloud Shadows, Sketch and Caustics

* When the camera is far from the world origin, flickering no longer occurs when looking directly along an axis

* Effects now support orthographic cameras

* Now support VR rendering (Single Pass Instanced, in URP only)

- UI for effects will now show a warning/notification if the primary parameter hasn't been overriden, or is set to 0.

* Clarifies why an effect is not visible.

* Primary parameters are now always at the top of the UI, for every effect

- Radial Blur, blur amount now stays consistent, regardless of the amount of iterations.

- Sunshafts now maintain a 1:1 aspect ratio

- Fog/Cloud Shadows/Caustics/Sun Shafts now automatically use the brightest directional light (Fog Light Source and Sunshaft Caster components were removed).

Fixed:

- Project from sun option (Caustics/Cloud Shadows) not having any effect in Forward rendering.

- Color Grading LUT, color inversion not actually correct when using Linear color space

- Installer errors when using the asset as a package

2.1.9

Changed:

- Scripts for the Post-processing package and Universal RP are now both in a package. By default, the asset contains neither and must be unpacked based on what's being used

- Retired support usage of the Post-processing package with URP 7. This greatly simplifies the code-base.

Fixed:

- Situations where Unity can crash when importing the URP package

- Errors in 2021.2.0 beta regarding GetDisplayTitle, due to changes in the volume framework

- HueShift3D, shader error when building to PS5
