Decal Collider v1.1.0 (18 Dec 2025) introduces a powerful, one-click solution for generating precise visual meshes and matching MeshColliders from decals, with full support across Unity’s render pipelines including Built-in, URP, and HDRP. The tool automatically trims colliders to the decal’s alpha channel, ensuring pixel-perfect hitboxes that match what players visually see—eliminating invisible gaps and oversized hitboxes.
Key features include:
- One-Click Build: Select a decal and hit Rebuild to generate both visual mesh and collider instantly.
- Pixel-Perfect Colliders: Colliders are precisely trimmed to the decal’s alpha, ensuring accurate player interaction.
- 18 Projection Directions: Supports forward, inverse, box, hemisphere, and more for flexible decal placement.
- Live Scene Handles: Adjust position, rotation, depth, and mesh offset directly in the Scene view.
- Runtime API: Full C# API with XML documentation for procedural decals, analytics, and object pooling.
- Stats Panel: Real-time display of triangle count, ray count, build time, and memory usage.
- Undo-Safe & Prefab-Friendly: Fully compatible with Edit & Play mode and Prefabs.
- Zero Runtime GC: Optimized for mobile performance with no garbage collection overhead.
- Cross-Render Pipeline Support: Works seamlessly in Built-in, URP, and HDRP pipelines on Unity 2022.3 LTS and later.
The package includes the core DecalCollider component, custom editor tools (inspector, gizmos, beam visualizer), demo scenes featuring world stickers and a map, comprehensive documentation (PDF and online), and sample textures under CC0 license.
Integration is straightforward: import the package, add the DecalCollider component to any scene object via the Inspector, and click Rebuild to generate the mesh and collider. Runtime control is also available through DecalCollider.Build(), RebuildSafe(), or the fluent API.
