Instant Destruction - Easy GPU Fracture

Instant Destruction is a GPU-powered toolkit that easily turns static props into highly satisfying interactive mechanics using a simple C# component script and lightweight GPU physics.

Features

--------------------------------------------------------------------------------

1. Dynamic Game Feel

Fragments shatter dynamically based on where the impact occurs. Featuring a striking hit flash with a subtle delay, and directional scattering that follows the impact force, it delivers rewarding visual satisfaction.

2. Zero-Spike Performance

Leverages Compute Shaders and Shader Graph to offload heavy calculations.

It prevents sudden lag when objects shatter, keeping the Main Thread free for smooth frame rates.

3. Just attach the script

We’ve packed all the heavy lifting—complex mesh analysis, memory management, and shader linking—under the hood. Get maximum visual impact with minimal properties, featuring a built-in auto-reset for easy map gimmicks.

Technical Structure

--------------------------------------------------------------------------------

1.C# Script

Responsible for mesh topology analysis, memory allocation, lifecycle management, and drawing the Custom Editor Window UI.

2.Compute Shader

Executes parallel computing for fragment transformation matrices, initial vectors.

3.Shader Graph

Processes vertex-stage trajectory animations and fragment-stage visual effects based on Compute Shader outputs.

4.Particle System

Triggered via C# lifecycle events to emit simple line effects expanding radially from the impact point.

Important Information & Notes

--------------------------------------------------------------------------------

Mesh Read/Write Required: To analyze and build GPU fragment buffers, the target model's import settings must have "Read/Write" enabled (includes an automatic built-in console warning to help you double-check).

Per-Polygon Shattering: Optimized for lightweight performance, this system treats each individual triangle as a single fragment. It is designed for fast, optimized prop destruction rather than complex real-time Voronoi fracturing.

Production-Ready Warmup: Pre-warms the system for a few seconds at scene launch, preventing asynchronous shader compilation stutters to maintain smooth gameplay during actual destruction.
