v1.4.3

Unity-SpriteAssist v1.4.3

Bug Fixes

• Parallel Import: Under Parallel Import, Unity Default mode sprites read the triangulation library from a stale ScriptableSingleton value in import worker processes, so the SpriteRenderer geometry did not match the inspector preview and Mesh Prefab. The triangulation library is now read in a worker-safe way during import, keeping SpriteRenderer, preview, and Mesh Prefab consistent.
• Importer outline pivot: Sprite Editor custom outline vertices were offset for sprites with a non-center pivot (e.g. bottom pivot). The pivot offset is now applied when converting outline coordinates.

Changes

• Unity Default modes now always apply SpriteAssist triangulation from the importer outline. The Apply To Unity Default toggle introduced in v1.4.2 has been removed.

v1.4.2

Unity-SpriteAssist v1.4.2

New Features

Apply Triangulation Library to Unity Default Modes

• Added Apply To Unity Default in Project Settings > SpriteAssist > Library
• Unity Default modes now use SpriteAssist-generated outlines and the selected triangulation library by default
• Disable Apply To Unity Default if you want Unity Default modes to keep Unity's native sprite geometry
• Default Transparent and Default Opaque creators now override source sprite geometry when the option is enabled, keeping SpriteRenderer and Mesh Prefab output consistent
• Existing sprites need a manual reimport (or Reimport All) after changing this option

Documentation

• Updated README triangulation library notes to document the Unity Default mode behavior

Full Changelog: v1.4.1...v1.4.2

v1.4.1

Unity-SpriteAssist v1.4.1

Bug Fixes

Fix NullReferenceException during legacy settings migration

• Fixed a NullReferenceException thrown on editor load when migrating the legacy Assets/Editor/SpriteAssistSettings.asset (introduced in v1.3.0)
• Calling AssetDatabase.DeleteAsset directly inside [InitializeOnLoadMethod] triggered Unity's internal RenderPipelineGlobalSettingsAssetProcessor.OnWillDeleteAsset before SettingsWindow.GetCurrentProvider() was initialized, causing the exception
• The deletion is now deferred via EditorApplication.delayCall so it runs after editor initialization
• Deletion is wrapped in a try-catch and retried on the next domain reload if it fails, preserving idempotent migration

Full Changelog: v1.4.0...v1.4.1

v1.4.0

Unity-SpriteAssist v1.4.0

New Features

iShape Triangulation Improvements

• Added Edge Smoothing to the PathSanitizer pipeline for iShape triangulation, producing smoother mesh outlines
• Improved edge case handling in TriangulatorIShape to prevent degenerate triangulation on complex sprite shapes
• Added Log Fallback Warning option in Project Settings — logs a warning when the triangulation library falls back to an alternative method

Parallel Import Support (#65)

• Moved external mesh prefab update logic from OnPostprocessTexture to OnPostprocessAllAssets to correctly support Unity's parallel asset import pipeline
• Added Parallel Import toggle in Project Settings (SpriteAssistSettings)

Bug Fixes

Fix "No vertex found" error for Dummy Sprites

• Fixed an error that occurred when processing Dummy Sprites (e.g. cloud(Dummy Sprite)) which have no geometry, causing SpriteUtil to throw a "No vertex found!" exception

Internal Refactoring

These changes do not affect runtime behavior but significantly improve code maintainability.

• Extracted mesh prefab lifecycle logic from SpriteProcessor into a dedicated MeshPrefabService
• Split SpritePostProcessor into separate responsibilities: mesh update and asset rename
• Introduced SingleMeshCreatorBase to consolidate duplicated mesh update code paths
• Separated sprite geometry operations from mesh prefab update responsibilities
• Deduplicated SpriteImportData constructors via constructor chaining
• Added an asset import worker process guard helper in PrefabUtil

Documentation

• Added iShapeTriangulation library overview and usage details to README

Other Changes

• Project Unity editor version updated from 2022.3.69f1 to 2022.3.62f3

Full Changelog: v1.3.0...v1.4.0

v1.3.0

Unity-SpriteAssist v1.3.0

New Features

New Triangulation Library (#16)

• Added iShapeTriangulation as an alternative to the existing LibTessDotNet
• Default library selectable via Project Settings (Default Triangulation Library)
• New input path preprocessing pipeline: PathSanitizer, SelfIntersectionFinder, ShapeGrouper, TriangulationGeometry
• Refactored to a strategy pattern via ITriangulator interface (TriangulatorLibTessDotNet, TriangulatorIShape)

Vertex Welding Option (#38)

• Added Weld Vertices option to improve normal mesh quality by merging adjacent vertices

New Resize Tools (#75)

• Resize functionality reorganized under Assets/SpriteAssist/Resize/
• To Multiple of 4: Scale Textures / Expand or Crop Textures
• To Power of Two: Scale Textures / Expand or Crop Textures

Bug Fixes

Fixed ScriptableSingleton already exists error (#73)

• Moved settings asset from Assets/ to ProjectSettings/ to prevent duplicate instance import
• On editor load, automatically migrates legacy Assets/Editor/SpriteAssistSettings.asset to ProjectSettings/ and removes the old asset

Other Changes

• Minimum Unity version bumped from 2021.3 to 2022.2
• Added com.unity.collections 2.2.0 dependency (required by iShapeTriangulation)
• Updated project Unity version from 2022.3.55f1 to 2022.3.69f1
