Version 1.8

Added support for Unity 2022.2. This required significant work to get things running in URP14, which contained a number of breaking API changes.
Added support for scene ambient light and SH probes. The AmbientLight property now has an alpha channel - use this to control blending between scene ambient light or the color specified by the AmbientLight property.
Added weights to control how vertex colors should be used (e.g. emissive, diffusive, or not at all). Vertex colors are used to store per-particle color by unity's particle system.
Added an example scene with randomized materials to give an idea of how to achieve different looks.
Added a global shader variable (float) _ProPixelizer_Pixel_Scale, which can be used to change scale of all ProPixelizer materials.
Added keyword toggle to enable/disable dithered transparency when alpha < 1.
Reintroduced alpha clip threshold property.
Fixed depthAttachment error on Mac/Metal
Fixed inconsistent dither pattern over large objects.
Fixed line artifacts on extremely high resolution screens.
Fixed artifacts when URP RenderScale is not 1.
Fixed Preview window not working in some versions.

Version 1.7.1

Fix NullReferenceException in material inspector when using package downloaded from UPM via engine version less than 2021.3.6f1 in 2021 and 2022.

Version 1.7

Added [MainColor] property attribute for PixelizedWithOutline shader.
Added option to snap object angles in camera space, to help create a 'billboard' effect.
Added Alpha support for Edge Highlight Color - set alpha to zero to disable edge highlights.
Added an example showing camera stacking setup, and how to avoid creep on moving cameras.
Added tool to the shader GUI to detect if materials need to be upgraded, and to handle upgrade.
Added _EmissionColor property. _EmissionColor is multiplied by the emission texture to determine unlit appearance. It's great for damage flashes!
Added additional messages to warn users when they haven't set the RenderPipelineAsset in the Graphics or Quality settings.
Added Palette option HSV_Weighted_SquareDistance.
Added Larger selection of preset dither patterns.
Fixed Mac M1 soft crash bug (caused by index out of bounds exception when sampling the 4x4 dithered order array for transparency).
Fixed no longer required to add shaders to the always included list when setting up the project.
Fixed support for vertex colors, so that particles are now colored.
Fixed Incorrect blending with transparent materials on some platforms/engine versions.
Fixed Some bugs in the RenderSnapable system, added new features.
Fixed annoying console error messages from incorrect PostProcessPass format.
Fixed unpixelized objects appear pixelated when occluding a pixelated object.
Fixed objects dithered using _BaseColor.alpha < 1 will now no longer prevent objects behind them from being seen.
Fixed Null reference exception if user has render pipeline set in GraphicsSettings but not in QualitySettings.
Fixed material properties have been given more sensible names (e.g. _Albedo instead of Texture2D_FBC26130). Examples have been tidied, with example separate appearance and outline materials removed. I've added migration tools to enable material properties to be automatically upgraded through the inspector.
Fixed Saturation/Value weights in Palette.
Fixed Disappearing materials when opening Unity (caused by UsePass in PixelizedWithOutline failing to import forward rendered passes from the shader graph if imported before the shader graph).
Fixed RTHandle support required for 2022b (URP 13.1 and higher).
Removed the Object outline shader, added OutlinePass.hlsl.
Removed Option to choose source buffer used for pixelisation. ProPixelizer now always uses the ProPixelizer buffer.
Renamed Pixelized to ProPixelizerBase and changed the shader GUI to redirect users to use the PixelizedWithOutline material instead.
Dropped support for 2019 LTS, remade all example assets (e.g. Render pipeline, post process data, shadergraph) in 2020 LTS.

Version 1.6

Added outlines now respect color palette, per-object control.
Added outline appearance now controlled via shadergraph (add your own dashed patterns, blinking outlines, etc!).
Added interior outlines using normal/depth post processing, per-object control.
Added color property to the ProPixelizer shader.
Added ability to define curve for mapping when using palette style V_Nearest (for monochrome palettes).
Added Support for HDR.
Added Fixed time delay mode to stepped animation tool.
Added Ordered-dither transparency (e.g. for fading objects in/out)
Added Option for camera snap to use orthographic size defined on camera, rather than just pixel size in world space units.
Fixed Post-process does not flatten depth buffer, works with transparent again.
Fixed Specular highlights no longer appear for very bright light sources.
Fixed Shadows work for multiple cascades.
Fixed Stepped animation tool doesn't create a new UUID when regenerating clips.
Fixed SRPBatcher now works properly with ProPixelizer Appearance+Outline material. You should see a performance improvement!
Fixed Additional light shadows (for URP 11+, thanks to Cyanilux's excellent repo.)
Fixed Incorrect color grading on linear color space.
Fixed Color grading bug, color grading is now 1-1 and limited only by 16-color/channel bit depth.
Fixed Pixelization post-process for overlay cameras (requires Pixelisation source to be set to 'ProPixelizer Metadata', URP 10.5+).
Fixed Camera snap supported for multiple cameras.
Fixed Camera snap for moving cameras.
Tidied up the example ShaderGraph, added more useful subgraphs.

Version 1.5

Added improved workflow for palettes. Individual palettes are now assets, so the values used for generating LUTs are saved.
Added editor tool for user-defined 4x4 dither patterns.
Added editor tool for creating stepped animations, to help replicate a flipbook/spritesheet feel.
Added Support for RenderScale
Fixed Bug for game view on Metal.
Fixed (for 2020+) Correct pixelation for material preview, material icons and shader graph preview.
Fixed (for 2020+) editor warning when selecting in inspector.

Version 1.4

Added dither pattern support.
Added single material to produce both outlines and appearance.
Added example scene (Floating) to show new shader and a no-creep setup.
Fixed occasional 'tearing' due to numerical precision error.
Fixed creep in rare cases.
Improved Palette Builder tool.
Made shader keywords consistent - run Window/ProPixelizer/Verify Materials to fix broken materials.

Version 1.3

Added option for depth-tested outlines, to prevent outlines when objects overlap (see option in render feature).
Added alpha cutout support.
Added custom GUI for Appearance materials (for ShaderGraph versions that support it, 2020+).
Fixed Object flashing bug for Orthographic projections when near plane was negative.
Fixed gaps at screen edge.
Fixed various truncation warnings.
Fixed support for Unity 2020.2 and URP 10.2
Performance improvement: Large performance improvement on all platforms (3 pixelation passes for color/outline/depth now reduced to a single 'Pixelization Map' pass).

Version 1.2

Fixed creep/malformation at some resolutions.
Fixed tearing in perspective projection.
Fixed 3x3 pixelation on AMD+openGL targets.
Quality of life: the '_ID' property in the ObjectOutline shader is now specified as integer in the range (0,255). No change is required if using the OutlineControl MonoBehaviour.
