Full release notes

4.7.1

Improved shader compatibility with Unity 6.0.12 and later.

4.7.0

Per-object Outline feature in Stylized Surface: outline shader pass is now applied using a custom Renderer Feature (as opposed to additional object shader pass). This significantly improves performance of per-object outlines and supports SRP batching.
The migration to the new per-object outlines happens fully automatically when you view the Inspector of a scene object using the Outline feature.

4.6.1

Improved support for Unity 6.0.8 and later (including OUTPUT_SH4 error).
Fixed an issue with the Override Light Direction setting of the Stylized Surface shader.
General usability improvements.

4.6.0

Added Unity 6 Preview support.

4.5.0

Improved shader support of DOTS and the Hybrid Renderer.
Fixed shader variant stripping of the Stylized Surface shader.
Fixed alphatest for cutout mode of Stylized Surface shader.
Added ability to change blending of vertex colors to be applied after shading.
Improved rendering of baked lightmaps.
Fixed flipped baked lighting direction when using light probes.
Improved tooltips throughout the asset.

BREAKING CHANGE: We've changed the way baked lightmaps and light probes are applied. It now looks much more coherent with the cell shading stylization.

4.4.0

Added shader support for URP 17 (Unity 2023.3).

4.3.0

New! We've added "Fade With Distance" feature to the Outline image effect. If enabled, the lines become more transparent the further they are from the camera.

Inspector UI improvements for the image effects.

4.0.0 HUGE UPDATE!

Pixelation image effect (+ new demo scene) for a stylish low-res look
Mesh processor that generates perfectly smooth normals that greatly improve object-based outlines
New demo scene "Desert" showing a Moebius-esque style using the Outline image effect
Stylized Surface materials now support Local Space Height Gradients
Complete Inspector UI overhaul of Stylized Surface and Water shaders (+ tooltips on ALL parameters)

3.9.6

Stylized Surface shader now stylizes all additional light sources in Forward+ rendering path.

3.9.1

Fixed an issue where outline image effect would sometimes show the scene as grey.
Improved SRP Batcher compatibility in the latest versions of Unity.

3.9.0

Detail Maps! We've expanded the texture functionality in the stylized rendering to include detail maps. Now you have ability to layer two textures with independent blending settings.

We've changed the blending of the Albedo (Base) map to mix with the stylized shading in a cleaner, more visually appealing way.
Reworked the Outline and Fog image effects to correctly render in XR mode when using recent versions of Unity.

3.8.0

Improved object-based outline effect integration with the Curved World asset.

Improved support for Light Layers.
Improved support for SSAO in Deferred rendering path.
Fixed an issue with emission on textured renderers.
Improved the water shader inspector.
Improved shader variant striping for Stylized Surface, Terrain and Water shaders. This results in shorter build times and binary sizes.

3.5.0

Added support for Unity 2023.1 and URP 15.
Fixed shader variant stripping in Unity 2020 / URP 10.

3.4.1

Added support for dynamic lightmaps and debug display in URP.
Improved Terrain shader compatibility with the Forward+ rendering path.
Added suport for screen-space shadows and reflection probe blending in the Terrain shader.
The Buoyancy component now supports remmebering the initial rotation of the object.
Water shader UI improvements.
Improved the appearance of demo scenes Room and Wanderer.
Added two water materials to the Ocean Islands demo scene.

3.3.0

BREAKING CHANGE: If a water material uses foam with a texture, it might look slightly different with this update. The foam direction formula had a bug, which caused foam textures to be slightly stretched. This is now fixed.
Added support for Unity's new LOD cross-fade functionality.
Added support for the Forward+ rendering path.
Fixed depth outlines in the Outline Renderer Feature.
Fixed rendering of shadows on the Water shader.
Fixed tiling of water when using a foam texture.
Fixed an issue where sometimes the Outline shader pass was not properly disabled, causing SRP Batching to break.

3.2.5

Fixed water rendering in WebGL builds.
URP demo scenes now auto-configure the URP Asset/Renderer. No maual configuration is needed anymore, removed actions from the Readme config section.

3.2.0

[Water shader] Improved compatibility with Xbox and PS5.

3.0.5

[URP] Improved performance of Fog and Outline image effect initialization.
[URP] Fixed a bug where image effects would stop working when changing Quality Levels at runtime.

Improved support of Unity 2022.1.

3.0.0

2.9.5

Improved rendering in the URP deferred rendering path.

2.9.0

[XR] The #1 requested XR feature is done - Outline and Fog effects now support Single Pass Stereo rendering. As far as we know, Flat Kit is currently the only asset with image effects that correctly support Single Pass stereo.
[XR] Fixed "Light Plane" and Skybox shaders compatibility with XR.
Updated light sharpness stylization for baked Global Illumination.
Added custom Terrain Material Editor for better integration with Unity terrain.
Improved how image effect shaders are referenced, now these shaders are not included in game builds if not used.
[Stylized Surface] "Receive shadows" toggle now uses the same keywords as Unity's standard shaders, making this setting survive shader replacement.
[Image effects] Outline and Fog image effects now use "Before Rendering Post-Processing" render event. With the new changes to these effects, this should work for all configurations.

2.8.1

Improved integration with the Curved World asset.

2.8.0

Improved compatibility with the Deferred rendering path.
[Outline Image Effect] Added an option for resolution-invariant outlines. If enabled, the line width stays constant regardless of the rendering resolution.

2.7.0

Fixed a shader variant stripping issue that was causing long build times and build sizes on Unity 2020.3-2021.1 and URP 10-11.
The Readme script now checks the project's color space and suggests a switch to display the demo scenes correctly.

2.5.2

The 'Shadow Occlusion' parameter now affects both shadow attenuation and distance attenuation, which means it works for all types of light sources.

2.5.1

Added a new parameter to the 'Stylized Surface' shader - 'Shadow Occlusion' which masks received Unity shadows in areas where normals face away from the light. This is useful to remove shadows that 'go through' objects.
