About this asset

Runtime CSG & Destruction Toolkit

Runtime CSG & Destruction Toolkit is a high-performance C# Job System & Burst-accelerated framework for performing real-time Constructive Solid Geometry (CSG) Boolean operations, procedural mesh shattering, and impact-driven mesh deformation directly in Unity at runtime.

Whether you are building destructible environments, real-time cutting mechanics, bullet denting, or procedural slicing, this toolkit provides a lightweight, dependency-free solution designed for high frame rates and zero main-thread hitches.

⚡ Key Features

  • Realtime CSG Boolean Operations
    • Perform Union, Subtraction, and Intersection operations between meshes dynamically during gameplay. 
    • Fast broad-phase spatial checks and robust triangle-clipping pipelines.
  • Procedural Voronoi Shattering & Fracture
    • Instantly shatter 3D meshes into physics-driven Voronoi cell fragments. 
    • Control fragment count, noise amplitude, scale, and surface jitter for realistic fracture edges.
    • Built-in fragment self-collision management to prevent PhysX depenetration explosions. 
    • Velocity inheritance allows shattered fragments to maintain parent momentum seamlessly.
  • Impact Mesh Deformation & Denting
    • Deform mesh geometry in real-time based on collision velocity and impact force.
    • Smoothfalloff calculations create realistic dent craters for metal, wood, or soft surfaces.
    • Configure hardness thresholds, maximum indentation depths, and dent radii.
  • Asynchronous Physics Rebaking
    • Offloads Physics.BakeMesh to background threads for asynchronous MeshCollider updates without stalling render threads.
  • Intuitive Editor Tooling
    • Includes a dedicated Editor Window (CSG Editor Window) and custom inspectors for quick setup, testing, and component management in the Scene View.

🚀 Performance & Architecture

  • C# Job System & Burst Accelerated: Heavy spatial calculations and mesh deformations are multithreaded across all available CPU cores.
  • Zero External Dependencies: Pure C# and Unity Mathematics codebase.
  • Platform Agnostic: Works on PC, Console, Mobile, and VR/AR.

🛠️ Compatibility

  • Unity Versions: Supports Unity 6+.
  • Render Pipelines: 100% compatible with URP, HDRP, and Built-in Render Pipeline.
