1.1.4 – Auto-Placement & Pipeline Reliability Update

🚀 New: Automatic Occlusionn Placement – On first import, Decal Collider now checks for Assets/Occlusionn and automatically moves itself there.
📂 New: Auto-Folder Creation – If Assets/Occlusionn does not exist, it is created automatically, then the asset is placed inside.
🧭 New: Dynamic Package Root Detection – Removed hardcoded path dependency (Assets/DecalCollider/...). The installer now finds Decal Collider’s real location dynamically.
🔄 Improved: Reimport-Safe Bootstrap – If the asset is moved during setup, installation resumes cleanly after Unity reload without user interaction.
⚡ Improved: Stable Pipeline Detection Logic – Render pipeline detection now uses a robust fallback chain (currentRenderPipeline → QualitySettings.renderPipeline → defaultRenderPipeline) for better Unity 2023/Unity 6 compatibility.
🐞 Fixed: First-Import Pipeline Trigger Failure – Resolved cases where URP/HDRP/Built-in package import could fail on initial import due to path/state timing.
🐞 Fixed: Legacy Path Installer Breaks – Fixed auto-installer failures when the asset was imported outside the old expected root folder.

1.1.3 – Pipeline Auto-Installer Update

🚀 New: Smart Pipeline Auto-Installer – The asset now automatically detects your project's Render Pipeline (URP, HDRP, or Built-in) immediately upon import and installs the correct shader/material package silently in the background.
📂 New: Project-Based Tracking – Installation status is now tracked via a local file (.installed.txt) instead of machine memory. This means if you delete the asset and re-import it, the system will recognize the fresh start and re-run the auto-setup automatically.
🔄 New: Zero-Interaction Workflow – Utilizing an optimized EditorApplication.update loop, the "silent installation" triggers only when Unity is completely idle and compilation is finished, ensuring a 100% crash-free setup.
⚡ Improved: Stable Detection Logic – Refined the GraphicsSettings detection bridge to ensure seamless compatibility between Unity 6's new architecture and older Unity versions.
🛠️ Improved: Asset Store Compliance – The auto-installer is now fully compliant with Unity Asset Store guidelines, ensuring no residual data is left in your scene or project settings.
🐞 Fixed: Import Trigger Issue – Resolved a bug where the installation wouldn't trigger during the initial import due to Unity's background processing; now handled with robust state-checking.
🐞 Fixed: Multi-Project Conflict – Eliminated "already installed" false positives that occurred when developers switched between different projects using the same asset.

1.1.2 – Unity 6 & Projection Logic Update

🔴 New: Advanced Projection Masking – In cases where at least one projection ray hits a surface, areas remaining in the void are now automatically clipped (masked).
🔴 New: Empty-Space Visibility – If the projection hits no surface at all (completely in a void), the Sprite, text, or mesh will now remain fully visible in its original form.
⚙️ New: PhysX 5 Safe Assignment – Added a secure mesh assignment mechanism to prevent physics engine crashes commonly encountered during the transition to Unity 6 and PhysX 5.
⚙️ New: Invalid Mesh Validation – Before sending mesh data to the physics engine, the system now performs an automatic validity check; if a mesh is "zero-volume" or invalid, the collider is safely disabled.
⚡ Improved: Standard Material Compatibility – The system is no longer restricted to a specific material; it now offers full flexibility, working seamlessly with standard Unity materials such as URP/Lit and Sprite-Unlit.
⚡ Improved: Mesh Projection Synchronization – Resolved code conflicts that previously caused Sprite or Text objects to momentarily disappear when switching to Mesh Projection mode.
🐞 Fixed: TMP & Sprite Visibility Issue – Ensured that SpriteRenderers or text objects are instantly detected and projected onto the surface during projection mode changes.
🐞 Fixed: Physics Mesh Cleaning Error – Resolved the "cleaning the mesh failed" error caused by complex TextMeshPro (TMP) meshes during the physics cooking process.

1.1.0 – The Live Link & Performance Update

🔴 New: Dynamic TMP Support – TextMeshPro objects can now be used as a source. The Decal Mesh automatically updates itself whenever text, color, or font size changes.
🔴 New: Sprite Projection – SpriteRenderer changes (such as flips or sprite swaps) are instantly projected onto the decal surface.
🔴 New: Live Update Interval – Added a timer (liveUpdateInterval) to limit the update frequency, ensuring optimal performance.
⚙️ New: Async Rebuild Support – Added the Coroutine-based AsyncRebuild(Action<float> onProgress) method to the API. This spreads the rebuild process over time to prevent runtime frame drops (hiccups).
⚙️ New: Save Mesh to Asset (Editor Only) – Added the ability to save the generated procedural Decal Mesh as a persistent .asset file in the project folder. This allows the use of baked static meshes without runtime calculations.
⚙️ New: Raycast Hit Callbacks – Introduced the RegisterOnHitCallback system, triggered whenever a ray hits a surface. Useful for playing surface-specific effects such as particles or sounds.
⚡ Optimized: Zero-Alloc Rebuild – Prevented allocation of new lists (new List<>) every frame during mesh generation. GC pressure is minimized by reusing cached lists such as m_CacheVertices and m_CacheUVs.
⚡ New: Dynamic LOD System – Added a distance-based optimization system that automatically reduces decal polygon count as it moves away from the camera (lodDistance).
⚡ Optimized: Frustum Culling – With the CullIfInvisible setting enabled, all calculation processes for decals outside the camera view are fully stopped, saving CPU resources.
⚡ Optimized: Texture Data Caching – Texture data used for Alpha Masking is now cached (m_TextureColorCache), eliminating expensive ReadPixels calls during every rebuild.
🎨 Improved: Editor Statistics Panel – The Inspector analysis panel has been revamped to provide detailed real-time data on triangle count, raycast hit ratio, and memory usage (KB).
🐞 Fixed: Physics Fallback – Added a Fallback Quad protection mechanism to prevent physics engine crashes if MeshCollider generation fails.

1.0.3 – WebGL Compatibility Fix

🐞 Fixed: WebGL build error caused by a missing platform definition in the API script.

1.0.2 – Hotfix & Stability

🐞 Fixed: Editor MissingReferenceException that occurred when a DecalCollider object was deleted before its delayed RebuildSafe() call executed.

1.0.1 – Hotfix & Optimization

🐞 Fixed: A performance stutter that occurred when spawning prefabs at runtime by preventing unnecessary mesh rebuilding.
